"you just add intelligence until you do"
So many assumptions. I'd challenge everyone to look deeply into learning theory and combinatorics. We have no reason to believe that intelligence is something you can just scale up without bound, and many reasons to believe otherwise.
For starters: nature "invented" intelligence hundreds of millions of years ago with the evolution of neural nets, and it's a powerful adaptation that confers significant advantage. Why are we the only intelligence with our level of analytical capability on Earth? If it were so easy to "just add intelligence," almost every large animal in nature should be capable of language, mathematics, and logic by now.
As someone who spent many years studying AI, machine learning, combinatorics, evolutionary theory, and related topics, some of the stuff that's been flying around about AI recently is making me itch.
