Lol. It really makes me wonder- what do you think real AI would look like?
Artificial general intelligence (AGI) refers to the hypothetical intelligence of a machine that possesses the ability to understand or learn any intellectual task that a human being can. It is a type of artificial intelligence that aims to mimic the cognitive abilities of the human brain

So it follows that the US $500B investment needs to yield >20% returns to have "achieved AGI". It seems a given regardless of development of what humans would typically think of as "intelligence".
So what happens if we don't reach it?
