  • Batteries (currently) are way too heavy for commercial planes. They can be used for the smaller propeller planes, but not for jets.

    I don't know what you were expecting to see to indicate activity. Flight tests are a pretty far along milestone, given the expense and time it takes to make a test plane. That nothing went wrong on the test flight is even more impressive, given that the engineering of using hydrogen in planes is still ongoing (as the article mentions).

  • There's a lot of activity on the hydrogen-fueled aviation front.

    The infrastructure issues for planes are way less. You need fuel available at airports, which significantly fewer and farther between than consumers require for cars. Planes (and least of the jet variety) already use specialized fuel they keep available at airports. The phase-in is a lot easier too, since most running planes only travel between a few airports in their route — so you'd only need the hydrogen fuel available at the airports hydrogen planes are using to start.

    There's certainly a lot of challenges to solve there too, but hydrogen remains the most promising solution for decarbonizing air travel.

  • Because batteries suck for any application where weight (ie. energy density) matters. Running long haul semis off batteries is not a super practical thing. Even with consumer cars, there are people for whom hydrogen will be a better fit.

    Basically we've been in a world where the happy medium of energy density and efficiency (gasoline) was used for everything. Now we likely need to split those things up into what energy density is more important for, and what energy efficiency is more important for.

  • On a side note, 1 Terapixel is just crazy. A square with 1 million pixels has this number of pixels. So, about 1000 of 1080p will fit into this square vertically and about 500 horizontally. How has such eyes to see this all pixel perfectly?

    If you zoom in on it (a pretty common thing to do with pictures) enough, most people.

  • I mean c-suite jobs (particularly CEO), are usually primarily about information coordination and decision-making (company steering). That's exactly what AI has been designed to do for decades (make decisions based on inputs and rulesets). The recent advancements mean they can train off real CEO decisions. The meetings and negotiation part of being a c-suite (the human-facing stuff) might be the hardest part of the job for AI to replicate.

  • It's gotta be a peer pressure thing, diplomatically, to work. The countries taking the biggest steps need to be loud about it so the ones dragging their feet (hi from the US) get their pride hurt if they don't take action. The ozone hole fix worked that way too (though of course that didn't have major political powers denying it was a problem).

  • An example of this in practice is Firefox addons. You need to get your extension signed for people to install it, but you can distribute it however. Mozilla of course doesn't charge for signing though. It's just to give them the ability to ban an extension found to be malicious.

  • There's still a good chance of a DOJ antitrust case against Apple coming that seeks allowing alternative app stores (and Apple's way of complying with the part of this case that went against them makes it even more likely, I think). But Epic's case is done, yes, unless they want to challenge Apple's compliance with the ruling.
