I'd put intelligence in quotes there, but it doesn't detract from the point.
It is astounding to me how willfully ignorant people are being about the massive aggregation of power that's going on here. In retrospect, I don't think they're ignorant, they just haven't had to think about it much in the past. But this is a real problem with very real consequences. Sovereignty must be occasionally be asserted, or someone will infringe upon it.
That's exactly what's happening here.
The current generation of AI is an opportunity for quick gains that go beyond just a few months longer lifespan or a 2% higher average grade. It is an unrealised and maybe unrealistic opportunity, but it's not just greed and lust for power that pushes people to invest, it's hope that this time the next big thing will make a real difference. It's not the same as investing more in schools because it's far less certain but also has a far higher alleged upside.
"Marginal cost barrier" hit, then?
