On your second point there is a further distinction between, can humanity create AGI and can a human design and implement an AGI. At present we are churning out intelligent beings at an alarming rate with little understanding of what we are doing. It’s a lot easier to imagine us creating an extended intelligence, manifestly without understanding it. Current work may even be a component of that. It’s this second more pygmalion concept that a human mind could conceive of an artificial mind and create it from its machines, that I find a little fanciful.
