  • I wouldn’t write off EV usage too quickly. The lithium batteries in EVs right now are around 160Wh/kg. The sodium batteries coming out of production lines now are about the same, but are also substantially cheaper, safer, and built out of more abundant materials.

    Yes, if you compare them to top of the line lithium batteries coming out of assembly lines now, they don’t look as good, but those batteries aren’t in actual cars yet. It’s very likely that we’ll see cheap EVs running sodium batteries, and they’ll often be good enough. We need more charge stations more than we need better batteries (as far as EVs go).









  • They want AGI, which would match or exceed human intelligence. Current methods seem to be hitting a wall. It takes exponentially more inputs and more power to see the same level of improvement seen in past years. They’ve already eaten all the content they can, and they’re starting to talk about using entire nuclear reactors just to power it all. Even the more modest promises, like pictures of people with the correct number of fingers, seem out of reach.

    Investors are starting to notice that these promises aren’t going to happen. Nvidia’s stock price is probably going to be the bellwether.
