to be fair, "AI" and "sentient AI" are two different things (growing up as a kid, I'd always conflated the two).

I'm very curious (but skeptical) that we'll invent sentient AI in the next few decades, but on the other hand I've learned not to underestimate the human race. I think the invention of the Internet is basically the Industrial Revolution 2.0. Being able to share and access knowledge from pretty much anywhere on the planet instantaneously is going to have an exponential effect on how quickly we make intellectual progress.
