to put things into prospective think of this. The world makes around 78 million vehicles per year. Think of how much materiel goes into each vehicle. what if I told you that if you parked each vehicle side by side in a huge parking lot it would cover roughly the same area as the needed solar panels? We do it every single year with cars.

You are right of course, if they start with everything at once, which they might for the super rich. We will likely see lower resolutions and/or display scaling for a while, as without content and quite frankly processing power to deal with potentially 100 million pixels is going to be huge.

The whole point of the article and my comment was this is not just some research paper. It uses similar tools and industrial processes that already exist.

This is materials science engineering at its finest. They have already proven it works and how to do it. Now they just need money to push it across the finish line.

Professor of materials science and engineer for whatever it’s worth.

I had a discussion here on reddit back in September (about two weeks before Tesla announced their new 1000V plug variant) where I went over specifically what limits their plug to 500V, and concluded it was primarily the airgapped distance between their high voltage pins, not the size of the pins themselves.

If you look at the technical specs that they ended up releasing two weeks later where they introduced their new 1000V-capable variant, you'll notice that the most noticeable change between the 500V variant and the 1000V variant (see pages 16 and 21, specifically), is that they've recessed everything relating to the HV connections back into each side of the connection about 5mm; which adds about 10mm to the airgap, which is more than sufficient to safely extinguish a 1000V arc before it can bridge the pins.

Notably, though, the thickness of the pins themselves is unchanged in the 1000V variant. I'm not going to do the math right now but I wonder if that pin gauge is what holds their new connector design back from being >1000V capable because increasing the airgap alone should buy them plenty of safety headroom (but I'll also admit I'm not intimately familiar with the necessary safety margins they'd be aiming for).

Yellow Pages is different from Google because there is no targeting of the advert. If there was a Yellow Pages tablet, that showed you ads for/against abortion (choose whichever you disagree with) repeatedly around every trade you looked up (plumber, chiropodist, lawyer, etc), then yes, it would be similar and I’d have a similar problem with it.

It is Google’s praxis of directing ads to targeted groups, coupled with the vulnerability of some of these target groups and the willingness of otherwise-aligned parties (the anti-abortion group, here) to pay Google to do this - all three combined are the problem here. I don’t think Google gets a free pass.

I know they dropped the “Don’t be evil” mantra, presumably the ability to do things like this is why…

Yeah the other comments here talking about how this is revolutionary / terrifying make me roll my eyes because they act like we haven't been doing similar research for a long time. These tools just might make the process more efficient.

It's very exciting seeing ML put to tasks that open up new possibilities vs making current tasks simpler.
