  1. 2:42 It's a huge stretch to call anyone in the plastic industry nice. The 7 resin identification codes came into existence to alleviate the public concern about plastics being bad for the environment. And the sign itself was purposefully designed to look like the recycling symbol, to make people feel better about it. They even ran multi-million dollar campaigns per year to ease off people's minds. And despite new symbols being "revised" as full triangles over a decade ago, most plastics still look like the recycling symbol. And from the 7 codes, only the first 2 have been recycled. And of those, most of it was only recycled once. And here we are, with the plastic industry raking up profits and decades later it takes an outsider's effort to make plastic recycling viable. Nice, huh?

  2. Well, it turns out hydrogen is still not about to take off.

  3. We study bacteria, so we can just as easily be studied for whatever reason by more advanced life forms. 😆

  4. 18:53 Why would you mention that if you're not sure? Microsoft does sell Windows. So there I was, around 19 minutes in, thinking about what else you got wrong that I was unaware of. There are a few statements that I couldn't get onboard with, others were clearly labeled as speculations but I disagree nonetheless, and there's plenty of levelheaded thought put into this video. This is what makes it weird - you did take a careful and critical look at many aspects of the FSD, but you skimmed on some details that still lead you do conclusions/speculations. It's like you did it on purpose to get us to comment. :P Anyway, this was a nice video for people who allow themselves to think and look beyond hype and hope. But in the end I took my like back (didn't dislike, though) because what I would really like to watch is more about things that were properly considered and distilled, and less "minor mistakes" meant to drive comments.

  6. 3:32 🤣 What? F degrees are better because 30s=freezing, 40s=cold, 50s=brisk, etc? Temperature perception is different, then humidity also plays a role in this perception. How about using measuring units that don't rely on such arbitrary things? 0°C = water freezing point, 100°C = water boiling point. Easy to remember, right? Check out how 0°F was originally defined, because it would be challenging even for a scientist to remember the specific mixture used early on. Now try to convert F to/from C or K (the SI base unit of temperature) and remember that formula involving both multiplication and division. Converting C to/from K is just addition or subtraction of a constant number. Now remember how NASA blew up the Mars Climate Orbiter because some people simply cannot be bothered to use the metric system. Keeping the imperial system makes no sense. It needlessly complicates a lot of stuff for a lot of people.

  7. So... finally here, not really finally here. :P

  8. Repeat after me: It's stupid to truly believe that high speed rail is a mistake in America. There's an unholy trinity of problems: cost, ownership and maintenance. The advantages are huge when you can see things in perspective. Leave the huge problems aside and compare flight to rail. All the security checks and boarding are a huge bottleneck, regardless of what powers the aircraft. A train can arrive at a station and leave only 1-2 minutes later. Compare cars to rail, and see how when you have a large enough distance it's impossible to drive the cars as fast as trains go, so having high speed rail enables long commutes. With a functional rail network, people will value it and use it. We already know that most people hate rush hour and they would love to reach their destinations faster and safer. Americans love cars because... what else is cheaper and convenient? Cars and plans can't scale like high speed trains can. The oil and gas industry lobbied their way to building the US on roads, but that grip will die once EVs take over. Cost Before anything, the US has to brave up, take a hard look at what makes HSR so expensive, and blast all the bureaucracy from orbit to make it cheaper from the get go. Deregulate the insanity and make a federal framework for land acquisition, with special rules for national interest - fair acquisitions but in a timely fashion. Prioritize segments by population density, to lessen the financial burden until completion. And be brave to take some financial loss (at least some subsidies), if necessary, by favoring the obvious huge advantages and long term impact on the economy and society. Ownership If it's not publicly owned, that is a huge mistake. A public infrastructure has a single owner, making it easier to handle legal and administrative problems. A bad government is still better than several bad companies. Maintenance Stop being complacent, drop the excuses, just do it. You just can't tell me you're proud to be American when a huge public infrastructure is left to rot. What the HSR unlocks for the US is drastically underestimated by many Americans.
