Your answer is... MONEY. It is that simple. Fission has never been cheap, especially against gas or coal. Fission price has only increased and not decreased. You can only make it so cheap, because as South Korea proves with their scandal. Nuclear is only safe if everyone actually follows the rules. Proving people are following the rules costs MONEY! This goes before all the other political BS, and gas lighting and ignorant lies. If people could actually get the technology to be safer while decreasing cost then we would be using it no matter how weary people are of it. So your answer is simply. 🦀 Money money money money 🦀 - Mr Krabs.

AI will be useful. Maybe not in the ways we thought. Rarely does tech work that way though. Anastasia just did a video on new hardware with great potential that went way over my head. Millions of times more efficent than modern computing. I beleive right now we will not simulate the human brain anytime soon. I do not beleive we will give free thought to anything either. (Especially at random. If we make sentient AI it will be with purpose.) You all should look up the video. I don't think it is possible to make a digital brain. The brain might fire neurons on or off, but it varies in signal strength, and length. I think we will need a combination of analog, digital, and quantum to make one. I am starting to beleive the human brain does in fact use some quantum computing. The brain just uses 20 watts like WTF. If our brain can do it our computers can. Either way the AI hype is worth trying. I see no downsides.

Yeah she didn't explain really how it worked. Only that it does! How does it function? You entagle a mess of quibits, and then read them. Great. How do you ask a question to it? How do you know what is the answer or the answer is even correct? How do you control any of it? I mean I am glad she is excited yet I didnt hear much.

Dude the moon is a hell hole. Not much on there cept titanium and helium 3. Same problems as Mars but magnified. Like no gravity, and the notorious dust. I'm not even sure why we would even need to use it as a stop gas we can build space stations at legrange 2. Until we actually need helium 3. I mean especially if we can make relatively cheap premade inflatable modules. Someone correct me on why a moon is better than a space station. What is going to happen is first mining will become cheap enough. Then settlements. Only when resources are scarce will we feel the need to go out. That is how humans have always been. Personally I think Venus is the best bet for a permanent colony. Pressure is safe at 53 km. Air is denser so it would be easier to float. Has resources, abundant energy, and more importantly an atmosphere and 90% plus the gravity. We have no idea how humans will be with lower gravity. So the last part is important.

I don't get it either. Especially with improved manufacturing. I guess it has always been easier to design a nuclear reactor, compared to building it.

AI is a tool. Like any tool you can use it wrong or right, and what program you're using matters. I think the expectations of AI were just stupid high. Stock holders act like AI will soon wipe your arse, while making your coffee. The bubble is meant to pop. I heard great things from people who use AI for certain simulations. Predictive modeling, and analysis. Research. Data collection. Yet I am not sure if those are actually AI. Or they just call that, just because it is trendy! I think AI will be a great tool once we figure out the limitations.

Well I hate to break it to you. I guess AI hype is pushing QC hype due to QC making AI a lot better if done right. Also if you want more computing news. I recommend looking up stuff about photonic computing. A company called Q.Ant is already making photonic chips that can be installed into a regular server rack, right? They claim give them two more years before their chips rival Nvidia in performance. Which would be a godsend since it can battle their monopoly. Their chips due to the nature of photonics are smaller, and generate less heat for similar performance. Soon. So they say. For AI purposes only. Yet maybe Microsoft and Sony will stop being cheap computers, and start being specialized hardware built for only games. Remember when they actually did that! I wanna see PPUs or physics processing units. TPUs, and other specialized hardware in em. Wouldn't it be nice if games actually had physics again. Destructible enviroments. Character models who didn't clip, and had smooth animations inside the environment? With things like Gensisis only getting better. It will happen, but only if we have the hardware to actually do it.

I saw a documentary half asleep that had a small part talking about how smell, and quantum entangling could work together. Which is why we have such a powerful nostalgia when we smell certain things in certain places. I can't remember the mechanisms or anything else if they even went deeper. It just blew my sleeping drug addled brain. I was near death at the time sloooowly recovering so everything is vague about it. I apologize.

"Ah, I see no evidence of life before me on this frozen pond. Ha take that god and the multiverse. Our universe doesn't support life!" While I personally beleive life is just extremely hard to get started, let alone turn into a thriving intelligent species? These people here have too much time. Neither have proven anything. We have explored nothing of the universe. Our communications have basically not even gotten past our yard. What I feel like we should be focusing on is trying to have different slurries mimiciking exo planet conditions. See if we can get complex molecules sort of like how we've successfully created pre-RNA. I am not yet convinced Earth conditons are required for intelligence. I think life is perfect for us, because we evolved to it.

Yeah I never knew there was a problem with them exsisting either. I mean we have pictures of one! They are real! I figured they just had a collision path much like Earth and Theia(small planet that hit us to create the Moon). Yet the problem makes sense too. It is a good question on why aren't they iust orbiting each other.

Volumetric density and storage issues is why it is a joke. The ship for hydrogen sailed when lithium ion started getting better and cheaper. Now the race is for better batteries is on, and unlike hydrogen? They have so much longer for improvement to go. I don't know about you guys, but I don't really like 50% or more of my vehicles space be used for hydrogen. I also don't like worrying about leaks, and hydrogen in gas form leaks more than Lockheed Martin. I'm not saying there won't be any niche markets for it. Only that I would bet my money on battery technologies. And if I could have one energy wish come true? It is that we get 80% of the maximum therotical limit of lithium air batteries! Max therotical limit for those is 12.3k kwh/kg. Nearly as much as kerosene! (That is without air. So it would work much like a regular engine needing atmosphere to run. )

@bernardomacara6284 I don't see how that is relevant to what I am saying about hydrogen being a poor choice to power vehicles. So you think using electricity to make hydrogen for cars is better than just using said electricity to charge a car? Uh mate, I hate to break it to you. Making hydrogen takes a ton of electricity. That would be significantly worse for the grid. The national grid can improve. Even using the gas we do have to power a plant for electricity is still more efficent then using it in your car. ICE cars suck at converting power. Power plants are much better, and then you have the entire logisticsl chain of getting gas to where you can fill it up over just sending power through the lines. The power grid in America needs to be modernized and secured anyway. Luckily for us wind at least, and eventually solar have just become the cheapest form of new power!

@svr5423 Are you talking about theortical limits? Because I just don't see how you're saying batteries have not improved. Or that the technology isn't developed. Say that to Tesla. Or people in the lab working on newer batteries like Wrights, NASA, AND Ampirus. Are we living on the same planet? Stuck in the 90s when batteries did suck? How can you say the low volumetric density of hydrogen isn't an issue when it takes up most of the vehicle even when pressurized. I don't see millions of hydrogen cars on the road, but I see every single auto manufacturer making and improving BEVs year in, and out. Yet I do see that with electric, and for good reason. I also see a grid that is already there. If everyone in America used an electric car - it would be similar to the power draw of every American turning on an AC. We need 22% more power. Which is easily reachable as we slowly change versus making a whole new infrastructure. So please tell me where are these small tanks of hydrogen that can give a car 500 miles of range? Where are the light hydrogen cars? Oh and you can produce gas at home? How's that drilling rig going. Refining it in your kitchen? Hydrogen isn't there except for niche applications. We aren't even talking about the cons of fuel cells themselves. Like how expensive catalysts are or degradation. I advise you to look into battery technology that people are working on that is moving the technology forward beyond just Li Ion.
2
@bernardomacara6284 I've also talked with others in the energy sector. Sure there are challenges, and it will cost money, but hydrogen isn't the solution. It will be for niche uses. Yeah, we need baseline and peaker plants, voltage support, and frequency controllers. Yet we are also already making ways to combat issues. All the difficulties you just talked about will be fixed as issues come along like it always has. We aren't transitioning in a day. We need 22% more power if everyone in America suddenly bought an EV. Yeah we can do that as BEVs improve. It will be expensive. The grid is already a security risk and desperately needs modernization. Hydrogen cars are still nonsense, and it will be niche. By the way are you against Air Conditioning? Electric cars can draw less than a modern central A/C unit in a large home. 3,566kWh versus 1,500kWh (small house) to 4,950kwH(largder). Electric Furnaces and Electric Heaters take 3,100kwh. It is funny that I never once in my life seen people complain about appliances ruining the grid. Yet suddenly cars will doom us all to the stone age. BEVs plus solar and wind with nuclear just make sense.

Yeah I am a knowledgeable laymen, but don't understand how people much smarter than I can take a look at hydrogens volumetric density, and think, "Yeah, perfect. This is totally the energy of the future." Look I am not saying it won't have any niches. Yet I think if Hydrogen had any future as a storage medium for vehicles? That ship has sailed due to the myriad of battery technologies constantly improving I don't know about you guys, but I actually like 50% of my vehicles space not being used up for fuel. Also then the whole leakage issues. Side note. What is truly wild with hydrogen is how a liter of water holds more hydrogen then cryogenic liquid hydrogen! Now if some break through in some nano material that allows us to store hydrogen with the same density as water, and we figure out a way to break the bonds? Sign me up. Anyway unless that happens I see no solution to it. It was dead on arrival as far as fuel for driving is concerned. Battery technology has so much potential. Lithium Air is the energy break through I'm hoping to see happen. 12,300ish Kilowatt Hours per kilogram. That is nearly on par with kerosene, but with the benefit of using an electric motors effiency. Nuclear Power needs to find ways we can copy, and paste the plants so they don't go 100 billion over budget.

She's German. Yeah Columbus discovered the America's. You discover your wife has been cheating on you. You discover murdered bodies the next day. You discover something that has been lost, or not known.

@kennethferland5579 Technology will catch up, and capitalism will bring the cost of the stations down. I have zero doubts people will pay a premium for faster charging. Especially in cities with a high volume of cars per station, and for commercial or industry. Even public busses could benefit from a faster charger. I think there will be a variety of speeds. You'll have economic ones, and faster premium ones where you pay extra for the faster charging time. Competition between charging stations could also push for faster chargers, and bring the prices down. Anyway I won't speculate on a timeline. Side note. Charging stations need to go the gas station buisness model. Gas stations do not make most of their money off gas. They make money off selling something else while people go to get gas. Seeing companies putting up charging stations that look like parking lots is dumb. Put up a food joint, or even a trinket store that people can look around, and spend money while they wait. Put an arcade where people can play some games while waiting. Anything! The thing is? The density is crap on these. Better to have a bigger battery pack, and charge less often for slower. Not really saving time if you gotta go three times more a week to charge. Anyway fast charging is in high demand, and EVs kind of need it.. I have faith capitalism will find a way. PS. Speaking of gas stations. I haven't been to a Buc-ees yet, but they look awesome. More of that.

She is an angry woman who loves the attention of the alt/fake science people. She does not realize her experience isn't all of the science establishment, and blames others for her life choices. This video isn't bad. It is all the other ones. Yeah, I'm starting not to trust her on anything. I shouldn't even watch anymore. Which is sad. She was good for a long time till she started pandering to the fake science people.

Great filter is quite long! It is a miracle we made it, and simply evolved. May I bring up maybe peak civilization is simply making a matrix, and having your civilization in it under secret? An advanced matrix you couldn't seperate from real life if in it. Able to alter your memories. Able to be a god, and feel anything possible without drugs. Set it up so you wake up every X years to change it. Robots and a small population are left awake to take care of the pods. Why try to rule even a part of a galaxy when you can live off fusion from stars. Just send enough colonies and generational ship out to live to those who reject the matrix. Still make an AI that watches those branches of humanity of course. Don't want them coming back all war like or changed destroying your peaceful civilization. I would live in a matrix. Reality sucks. I definitely would be a demi god.

@petera2133 How is it harder these days than before? Easier than ever to speak your mind. People don't have to listen. Listening to the hive mind of Twitter or hive mind of any SM. Yeah Gates is right. People are stupid.

He speaks how I imagine a redditor mod does. "Um sir SURRR. Ashckully th tha that is sithmple not true you are wong." Hunched over pushing up his glasses snifling.

Depends. I suspect from a national security perspective or research. It will be important. Same with AI. It just isn't going to be ubiquotous.

Screw your flying car, and his fusion! Where the hell is my military exoskeleton? You guys don't want your own exoskeleton? Be able to flip multiple cars with ease, immune to small arms, and then run over 60mph for hours? Go toe to toe with humanoid robots? Or uh... Help build a house with no other construction equipment? Yeah you know you do!

Am I the only one getting no sound? Other videos do. Edit. Had to exit the app. Jesus. YT on Samsung is hot garbage. Every update fixes something then breaks two more.

Agreed for the most part. Nuclear is great for a small package. I think SMRs have a future for datacenters or AI. Yet the markets will go for whatever is cheaper. To me it seems like renewables and batteries are dropping like a rock year in, and out with no signs of stopping. Especially with pervoskites on the horizon. I do want to see nuclear plus TPV cells eventually become a thing. MIT has recently made some with efficiency that rivals turbines with zero moving parts. Imagine one day being able to stick a nuclear pellet into some crazy container made out of some super material that can withstand the heat, shield the radiation, and just have TPVs surrounding it producing energy. Maybe that can give us real small nuclear batteries. Well technically not a battery, but maybe something small enough to power an exoskeleton.

I think it is stupid. It is easy to pretend to be robot pretending to be human. Or confuse someone with some version of autism to be a robot honestly. Like that first person didn't answer normally. So of course we are going to assume it is a bot. Throwing AI into the wild like a chat room for two hours, and then at the end asking people who the bot would be a good test.

I would like to point out there are people alive today who thought a home PC was a dumb idea. Will quantum be mainstream? No. No I don't think it will in our life time. Now will it be used for more than what we think? Most certainly. We don't have leagues of people working on algorithms, or programs yet. I am basically saying there will be a lot more uses than what we can dream of. Eventually. I just can't tell you how long.

Sabine do a video on quantum navigation. It could make GPS redundant? If anyone is going to point out flaws in it. It is you.

I actually didn't know about the carbon capture. That is cool. Get rid of it, lol. Why isn't it already used? You know I never thought about what solid carbon looks like in the solar system. There will be no colony or base on Mars in the next 20 years. N Elon better be working on the next Rocket, because someone will catch up. I don't think Starship is enough to sustain more than a few. Next evolution of rockets is coming quick. Space X better be working on a full flow Rotating Detonation rocket. A few government agencies, colleges, and companies are working on em. One called a multi mode RDRE uses tesla valves to fix the fuel injecting problem, and a aerospike which I thought was neat. Future is going to be sick. Venus is where we should focus our sights on anyway. It has gravity, atmosphere, energy, resources, and closer. Floating inflatable space stations!

There is a company trying to use flywheels as a storage. It is an insane feat of engineering. Think it runs in a vacuum rotating at insane RPM. Flywheels for fluctuations with batteries plus super capacitors will be the future. It won't be one technology most likely for a while. There is a company that is working on the frequency or fluctuations I think with battery and super capacitor technology. It won't be the main storage. Just help the baseline or something like that. I mean why we don't do nuclear for baseline then decentralize the grid with renewables is beyond me.

@RandomForestGump I know what you mean... Yet sometimes people need a slap of reality. I am seeing overblown expectations that even my layman mind knows is wrong, because I think some want funding. So the researchers have to play a game of manipulation in order to get it. Sort of like how channels use click bait to get attention, because it works! Especially versus being honest. I'm sure there are a few downright fraudulent companies running amok. Raising expectations so high always has a backlash. I expect it both for AI and Quantum computers. Yet! I hope I am dead wrong. There are a lot of promising theories and technologies in their infancy. I just think timeliness are off. Photonic computing, and eventually quantum photonic computing looks great if we can get it to work as some way it will.

@svr5423 Sorry about the other post. I couldn't see the read more as it loaded blank at first, and now I can't see my comment to delete it. What do you mean we had lithium batteries since the 90s? Yeah, and the first transistor was made in 1947. What does that mean? Technology improves. I can't link any, but if you look at battery density, weight, and cost charts. Everything is improving dramatically. We already have 750kwh/kg batteries coming, and solid state batteries in production cars this year. While volumetric density for hydrogen is not improving. Is it? Can't beat physics. That is my issue. Charging times are improving significantly. Batteries can charge in around 25 minutes now, so 20 minutes longer without the fear of leaking. You know what I see when I go outside? A power grid! I don't see hydrogen infrastructure anywhere. I can also charge at home. Charge with a solar panel, or wind. I can charge for pennies on the dollar. Thing is pure EVs are just good enough for 80% of the population already, and give it five years for batteries to be good enough for other applications. Cost plus infrastructure is what holds most people from buying an EV right now. Hydrogen has no infrastructure at all, and costs way more to run, and maintain, and purchase. So basically all you have here is some weight and time to fuel up. Yet WEIGHT! ✋ The weight part isn't even true.. The Toyota Mirai weighs 4,335lb, and the Tesla Model 3 weighs 3,528lb, and Model S 4,766lb. That is with way less total cargo space by the way. So uh, my original point stands. I don't know about you, but 50% or more of my vehicles space being taken up is just stupid. Let us not forget how dumb it is to turn electricity into hydrogen just to transport it twice, to and fro, then get it just to turn it back into electricity.

Ironically, atheists can be one of biggest offeners of being adverese to the lack of being able to admit, "I dont know issue." Doubly ironic that it was while talking about the Big Bang theroy which is when I realized I am just a pea brained peasant. I am agnostic or some derivitive. Anyway some atheists believe in theroies as fact. I find it just as annoying as religious zealots.

@tubecated_development You are talking about the surface, and yeah that would be silly. Colonization on Venus involves living in the atmosphere which has three distinct layers. It is in the clouds! 31 miles or 52km up where I read is best where the temps, AND pressure are very similar to earth. Think it is 0-50c or 0-131f. Here is the kicker. A human inflatable colony would be able to stay in the air with just the air we need to breath. So basically we would float around, and use drones to do anything needed on the surface. You get the gist. Some people far smarter than me thought of it all, and so you should look into it. I think it is actually more viable than living like rats in Mars with crap gravity, and no atmosphere for protection. With that said it won't be easy. Living anywhere where the enviroment is so deadly sucks. Yet I bet my money we will see it.

Yeah unless we can make them super light then... I don't know. I read unsprung weight is a huge deal. Had a list of cons longer than yours from an engineer. Yet 20% effiency? Yeah for slow applications it sounds okay. For a car at highway speeds on terrible roads. I don't know. If I recall the suspension would have to be redesigned.

A friend and I saw an aircraft/UFO that I later found out looks similar to something called the Tr3-B. Look it up. It was Groton Connecticut 2006ish. It hovered silently for 5 minutes in the night sky where I could see the silhouette, and lights. 3 lights each corner with one weird one in the middle. After 5 minutes of us being like what is that. It took off like a bullet suddenly. Not a rocket or aircraft. I saw no plume or heard anything. It headed north before heading over the tree line, and then suddenly popped out heading east. That turn must have been HARD. It was only out of sight for a moment! Then it went over the horizon. The entire process took under 10 seconds from hovering to over the horizon. We could never figure out if was small, and silent. Or large, and high up. Yet just last year Sandboxx news Alex Hollins told his story of seeing one too which is just insane. He is a respected journalist. He said it was massive! I cannot explain that, and I won't. My friend says aliens, or dimensional beings. I don't know about that. I think Alex, my friend, and I saw the same thing. Yet I can't be certain if Alex saw a different craft. I swear by this story. Things like that make me agnostic life, and my friend crazy, lol. I just hope it is ours. Never seen any real UFO again sadly.
