Human body is insanely complex. Remember that we do not have actuators that can push, only pull. When you stand still, your muscles are working hard because your bones would twist all over the place and you would collapse if muscles do not keep you balanced at all times. This has some side-effects, too. Your neck can get sore if the muscles in your calves are too tight because all the muscles from your calves to your neck work non-optimally and your back will twist incorrectly as a result.

If Musk & SpaceX can actually deliver their promises, the Starship should be able to make the trip in half an hour. However, that will be so loud that it cannot depart or arrive near any city.

I agree. Finally somebody understands that the only realistic long term objective is to allow everybody to use more energy but do it in sustainable way. As for the sensible ways to do that, wind and solar need LOTS of energy storage capability, nuclear and hydropower are basically the only green energy sources that do not require additional energy storage. We should be building Tesla Megapacks or similar stuff everywhere right now. That's because nuclear (fission) power is not sustainable either with current light water reactors and all hydropower that can be practically built has already been built. The whole world could go with solar and wind if we had good enough energy storage capability. As in ability to store electricity for half a year. One possible solution is to build so much solar and wind that you can use extra electricity to generate artificial fuel (basically get hydrogen with electrolysis with water, combine with CO2 from various sources to generate ethanol which is very stable and easy to store for long term storage). Forget people talking about storing hydrogen. The tanks required for that are so expensive that it makes zero sense. The big problem with liquid energy storage (as in fully synthetic ethanol or methanol or gas or diesel or kerosine) is that we don't have fuel cell technology for the scale we need. We would need 500 MW fuel cells when the current state of art is close to 1 MW for hydrogen and probably way less than 0.1 MW for ethanol.

@a7699aaa Estonia used to lag behind Europe but they have improved a lot in recent years. Finland was the most advanced country in the 2000's but has been falling since (as a Finn, that is very typical behavior for Finland: once Finland has been declared the best in some catogory, Finns stop paying attention to that thing and focus on something else, and the thing that used to be best starts to detoriate). Just look at PISA 2003 vs PISA 2022 educational survey results to see the difference! It remains to be seen if Estonia can keep up their educational system or if they will follow the path Finland executed.

@davestagner I think flow batteries with huge tanks would be a nice solution in the long run for grid storage. However, we need to start doing something today and huge Li-ion fields are proven solution that does work. It's more expensive than some potential future solutions but those future solutions may still turn out to be sour. I don't think that we should build just li-ion systems in long run because that technology is obviously far from perfect, too.

@davestagner I totally agree. The reason I keep asking about efficiency is that when you combine electrolysis to generate the hydrogen, some yet-undefined process to convert hydrogen to combustible fuel and regenerating electricity after storage, you have to multiply efficiency of each step to get the total efficiency. I think you could get close to 40% for fuel to electricity step at least in theory, electrolysis is about 70% so these combined already puts max efficiency to 0.4 * 0.7 = 0.28 or 28%. The process that converts hydrogen to combustible fuel is only going to reduce the total efficiency. And I want electricity at all times, not only when it's windy or sun shines, so the whole system must be designed and implemented for the worst case situation. And that's when you have to generate your whole peak power purely from the fuel. And it currently seems that even 5x the price is way too much for the market to bear, which would be possible with 20% total efficiency. An max theoretical efficiency with energy storage system in fuel format is close to 28% as I explained above. If somebody can come up with a catalyst that improves the efficiency of electrolysis and we can produce e.g. high efficiency direct methanol fuel cells, then situation might change. A possible alternative is to simply manufacture 10x cheaper solar panels and use very ineffective process to generate the fuel for the storage and worst case usage. 10x cheaper solar panels do not happen fast, though.

@ColinKip Isn't training also giving artificial advantage against others? You cannot have any other regulation but arbitrary decisions, typically made by a committee.

@Leanzazzy I think they could give every driver 60 seconds worth of boost for the whole race. Then it would be tactics when you use the boost because you could obviously defend with boost, too, but if you use boost to defend when the other driver didn't actually use boost, your end of race will be harder.

@SoPeter216 Freedom of speech is about ability to share ideas and critique of ideas openly. It's not an open invitation to start attacks against specific people. Tommy Robinson attacked verbally Jamal Hijazi, got a court decision that would have required him to stop attacking but he choose to continue the attack anyway. Play stupid games, win stupid prizes. If Tommy Robinson had criticized the politics related to Jamal Hijazi instead of person, there would have been no problem. Also, claiming non-true things while attacking a person verbally doesn't improve your odds in court. Robinson accused Hijazi of violent behavior against English students at his school. The accusations were found to be false in court and in the end Robinson was ordered to pay £100,000 in damages and cover legal costs. Spreading non-true defamatory statements about individuals results in heavy penalties in most countries for a good reason. Do you have any other examples in mind?

4:37 I don't really understand the viewpoint of the people that argue that you shouldn't use robots because those take away jobs. Are they truly understanding that they are arguing that you shouldn't use machines because it takes away jobs? Are they also against excavators that obviously take jobs from shovelling? If not, I'd argue that they simply haven't thought it through. Let machines do the work and let humans to have more free time if there are no jobs. Of course, that requires changes to social support systems. I think the answer is Universal Basic Income (UBI) but if somebody has better ideas, I'd be happy to learn about those.

Fracking for geothermals makes sense if you actually use potable water only. The problem with that combined with high temperatures is that it's really corrosive and can cause minerals for detach from the ground and mess all nearby ground water. In addition, that's really corrosive to the pumps and piping, too. If you can handle all those issues, I totally agree that fracking for geothermals is the way to go.

@rjfaber1991 I agree that I presented a bit simplified version but the major point I was trying to express is that we need energy storage systems. Everything else is easy and there're lots of possible solutions there. And I totally agree that we shouldn't use just a single method for everything.
2
@rjfaber1991 I think we mostly agree, indeed. As for the hydrogen, I think it's poor storage medium but it might be usable for short term storage when you don't need lots of storage capacity nor high current output. The problem with pure hydrogen is that you have to keep it really cold or it cannot stay in liquid form. And in gaseous form it leaks through even metal walls and requires really heavy and expensive tanks. One interesting behavior of pure hydrogen is that even in liquid form it contains less hydrogen per litre than ethanol in bucket in room temperature. That alone is enough to make it pretty poor energy storage medium. As an extra problem for hydrogen, the fuel cell technology is still highly expensive. Unless I've misunderstood something the fuel cells are even more expensive than the hydrogen tanks. And I'm talking about "green" hydrogen here (that is, hydrogen created with electricity instead of from natural gas or other fossil sources). If you still have some fossil processes that output hydrogen as side-effect, it's definitely sensible to use that hydrogen for energy instead of venting it into the atmosphere.

@vblaas246 Is there any public info about real world efficiency of that process? How much electricity is needed to store energy as fuel and convert is again to electricity? For example, if you put 10 kWh electricity into the process, how many kWh are you expected to be able to recover after the fuel is stored for e.g. 3 months? Is the total efficiency even 20%?

@SoPeter216 As long as you can publicly use freedom of speech and still keep your freedom, things are pretty good. Russia and Belarus are examples of places where you cannot safely use freedom of speech publicly. US, Germany, France and UK are still places where you can publicly disagree with any decision made by the current leaders and can publicly suggest alternative solutions without risking to be thrown into a prison.

The XR Stage was easily the most interesting tech in this video. Unfortunately, it's also the tech that will be the most expensive to implement in the long run so it might practically never get to hobbiest level. The other camera to 3D position technologies are already really close to being possible with a couple of random Android phones on tripods and some AI software.

Great production quality for this interview! I would have wanted to see more discussion about technology but hopefully you have follow-up videos about e.g. the technology of those glasses.

AI tools are such a performance booster that all humans working with visual art or images must learn to use those tools or they will limit themselves in equally small work segment as horse cart wheel builders these days. Some people may still make a living that way but you have to understand that the need for artists that decide to not use AI tools will be very limited. We have people still designing and building mechanical watches even though electrical watch with quartz timing is clearly superior for telling the time. Some people will be willing to pay for fully human powered art in the future, too, but that will be a really small minority.

I think it would be great to have a counterpart for this video talking about the research that Carl Sagan initiated where then modern research methods were used to try to detect life on Earth(!) and how most methods actually failed at that time. And it would be nice to then include info about how modern instruments e.g. that has been sent to Mars work today.

8:10 It's easy to see that Jensen Huang respected your effort making great questions. And I think this should be considered not that different to the end of interview where Jensen explains that the most important question working with AI is asking great questions. Imagine a situation where you would have a panel of tens of human experts waiting for questions to answer any problem you're currently having (this being the human analog of high level AGI or base level ASI), would you start by "so... do you know any fun jokes?" or "did you watch latest Kardashians episode?" or could you have better questions?

Honestly, it seems that even alcohol causes so much trouble in the world that maybe even it should be allowed supervised only. Some people keep talking about responsible usage and still do not accept that supervised usage could be the only way that works for everybody.

I think the example there the tip of the shoe was on the offside is a great example that the only sensible option is to have this clear definition of the rules. As a result, the ruling was definitely correct that the player was offside. If you create any other rule such as "more than 5% of the player offside is a foul", then you can find some example where the player was 5.01% offside and you would have the same discussion about the rule. If you don't want clear definition, then you would have to use some kind of random number generator to randomize the line and I think it would be much worse for the players. It might be more entertaining to the viewers, though. I guess it all boils down to "why do we have professional sports at all"? If you think it's mostly entertainment, then the correct solution is to have some randomness in the system. If it's about finding the most competent athletes, then you want clear boundaries.

Great video! I think it basically boils down how religious you're. If you look at things just from the scientific view, it should be obvious that artifial womb is something that we should try to create. And I strongly believe that we'll get that technology within our lifetime because I'm currently thinking that we'll get superhuman AI within our lifetime and that will be able to solve the artificial womb technology even if we cannot do that. The bigger ethical problem is what kind of spare parts it's okay to grow. Again, if you're religious, the answer is nearly none. And for atheists, the answer would be any, including the whole body. That will cause huge conflicts in the next couple of decades. All that said, in long run we should decide if we still want to evolution in homo sapiens. If we allow any born people to keep living practically forever and reproduce no matter how bad their genes are, the results will be pretty poor in long run. We already have the technology to prevent any evolutionary effects on human race – the question is if we want to use that in grand scale. For example, from evolutionary standpoint, women should have wider hips even through current fashion trends may suggest otherwise. As such, we should prevent women with narrow hips from reproducing that much because we've removed the evolutionary pressure from dying to giving birth because of having too narrow hips. However, it doesn't seem very popular that you shouldn't have kids because that would be too dangerous without modern medicine. Instead of sterilization, we allow such people to reproduce and carry the problematic genes forward. If we keep doing this for long enough, artificial womb is the only solution we have.

2:56 Looking at those stats as a Finn, it's pretty safe to say that Uruguay and Turkey probably stuff extra ballots into the votes because it makes no sense to have such high voter turnouts in reality. And I would also susped Peru, Indonesia and Argentina results for the same reasons but those are borderline believable because it's close to number for Sweden where 80% is definitely believable. And that list is missing Russia which typically has official numbers around 90%, too, for exactly the same reasons.

As an European, I love to watch things like this to understand failed examples around the world so we might be able to avoid repeating already failed experiments. Those that fail to understand history are doomed to repeat it.

I totally agree that if this V1, then V10 will be pretty good. However, given all the limitations of V1 and really expensive retail price, will there be enough paying customers to make V2 possible with the same or similar tech? Oculus Quest was the first really successful VR headset and that was thanks to being cheap enough while having acceptable quality. This is like total opposite of Oculus Quest and that was the successful product. Imagine if the first iPhone would have been $3500 instead of $499 for the base model or $599 for the model with slightly bigger storage.

@jonb5493 Which fuel cell allows 50% RTE? Does some real world hydrogen car have that good fuel cell setup?
1
@jonb5493 I think best modern car diesel engines have efficiency near 40% and theoretical max around 55%. Of couse, those numbers can be achieved with only one optimal RPM for a given engine so real world efficiency will be less because you want to control the RPM.

@drjojo5551 You can definitely get enough total energy from wind and solar if you have good storage system for the energy. The problem with wind and solar is that those energy production methods are really unstable and depending on where you live, the total production may be nearly zero for weeks or months at more or less random times. You have to use energy from energy storage for that time. Right now, Australia has maybe the most advanced electricity storage systems and their setup lasts about 5 hours nationwide if I remember correctly.

Voting multiple times still cannot prevent attacks via the digital counting system. If you cannot make votes inspectable by the voter (which cannot be allowed if you think your citizens might be physically threated if they "voted incorrectly", coersion with other words) then every voter must blindly trust the system to collect and count all votes accurately. All digital systems are vulnerable to supply chain attacks and nation level attackers with big budgets can do surprisingly elaborate attacks. If you can make votes public (that is, open voting) and everybody can check the votes of everybody, then everybody can run their own software to validate the voting results and they can also verify that their own vote has been collected correctly in the public database.

Sporting regulations will always be totally arbitrary. If you wanted to be totally fair, you would also ban all kind of training because that obviously improves performance! On the other hand, it seems that people are not interested in sports where you're basically comparing genes either which would be the ultimate end goal if you want to ban every performance increasing tech or method.

38:10 The question I'd loved to hear at this moment is "What kind of memory bandwidth and interconnect speed does this little DIGITS system allow?" Everything that Nvidia has disclosed about DIGITS this far sounds good except for the missing information about memory bandwidth and supported interconnect technologies in general. If those are too low, then DIGITS will be good only for very specific tasks even though it theoritically has a lot of computing power.
