I believe in Demmis when he says we are 10 years away from - from AGI.
He basically made up the field (out of academia) for a large number of years and OpenAI was partially founded to counteract his lab, and the fears that he would be there first (and only).
So I trust him. Sometime around 2035 he expects there will be AGI which he believes is as good or better than humans in virtually every task.
