I do think material science break throughs for carbon capture is the most sensical way to solve this. But huge space projects or chalk dust airlifts are cool too.

overpopulation is not a someday problem at all. Either it already was the problem and is the direct cause of global warming or you haven't been paying attention to demographics which show global population peaking in the 2050s because of India and China modernization.

yeah a lot of the emissions remedies seem to overlook the realities of geopolitics. "Just force people to do it", what with your gas guzzling jet engine Abrams Tanks? At a base level the militaries of the world aren't giving up carbon and we only have like 2 decades left to do something.
We either need to to remove the carbon, affect the albedo of the earth, or deflect radiation coming to earth. Or all 3.
Deflecting radiation is a large engineering project. Maybe you should try to send a fleet of sun shields to the L1 Lagrange point. Or maybe you should try to pump large amounts of chalk dust into the atmosphere. I'm unsure what would be the better use of time. I've read that even just painting all the roads white buys us a few years.
Of all these possible solutions, the sun shield at the L1 Lagrange point might be necessary for humanity beyond just applications of global warming. It sounds big and ridiculous, but we really should consider it.

you only charge on road trips. Charging at home has no analogue with gas cars... It's just something that's intrinsically better about EVs

I don't think TSLA will go to the moon soon, the corporate strategy seems to be to attack competitors on margin and go for market share.

what. No it's not. TSLA PE ratio is like 70. A long time ago I didn't buy AMZN because of it's high PE ratio. That was a mistake.

Cool. Could this/similar sampling be used to initialize a Gaussian Mixture Model and speed that up too?

There were quite a few unintentionally hilarious moments. Some that stick out was Sam not having seen Ex Machina and then also Sam using the Elon Tears interview against Elon in a kind of Uno reversal move. Seems to be a weird rivalry brewing.
