If your argument about my gravity example holds. That’s not really a good argument. Between Newtons death and the first powered flight was almost 200 years. Being all negative about gravity would be reasonable since a bunch of stuff had to happen.

I’m not sure I buy your longer argument either.

I have a feeling the nay sayers are right on this. The next leap in AI isn’t something we’re going to recognise. (Obviously it’s possible - humans exist)
