I agree with this. It seems to be a huge hole in the entire discussion. It's not enough to cite historical data, and assert that exponential growth will continue indefinitely. I could speculate a bit about some explanations. But I'm curious if there are any good discussions out there, does anyone have some recommendations?

I also found it annoying that in all his examples of exponential growth biological system he conveniently left out where the populations crash after reaching an environmental limit. I think it's just as likely that technology will send us back into the stone age with nukes or bio-weapons as it is we merge with AI.
