At a U.S. average of 0.86 pounds of CO2 per kWh
In France, where two thirds of electricity production comes from nuclear plants, the carbon intensity is 10 times lower: 39 gram CO2eq/kWh. I'm not saying that this makes diamond dust a feasible idea, but using the US number is probably not the best choice in this calculation. To get an idea of the varying carbon intensity of electricity production around the world, see electricitymaps.com.
Average people aren't in any meaningful way a target demographic for this sort of stuff because for average people, food isn't a fashion statement. It's an expense.
I think price is precisely why this is going to be hugely successful. Making a meat equivalent directly from plants will eventually be a lot cheaper than feeding a cow for a few years. Right now it's still selling at a premium because the production scale isn't there yet and they can't keep up with demand, but give it time. The price will get there.
Musk conveniently says that developing and manufacturing his super-chip itself will require raising capital
What is your source on this? According to the information given during Autonomy Day, the chip is already in all new model 3, s and x right now. And manufacturing of the chip doesn't require any Tesla capital expenditure because it's done by the Samsung fab in Texas.
On Earth, gold veins are produced by aqueous processes. You wouldn't expect that on asteroids. Platinum, and platinum-group metals, on the other hand-- these are siderophiles, and hence depleted in the Earth's crust. Good elements to look for in asteroids
Um, gold is also one of the siderophile elements.
