When talking with non-tech people around me, it’s really not about “rational minds”, it’s that people really don’t understand how all this works and as such don’t see the limitations of it.
Combine that with a whole lot of FOMO which happens often with investors and you have a whole pile of money being invested.
From what I hear, most companies like Google and Meta have a lot of money to burn, and their official position towards investors is “chances of reaching ASI/AGI are very low, but if we do and we miss out on it, it will mean a huge opportunity loss so it’s worth the investment right now”.
