Well, that depends on your definition of AI, of course. But using some definitions, we are having it in several forms like search engines, self-driving cars, and question-answering machines.
Personally I think that it is unnecessarily agrandising language. That AI has since improved independently of Minsky does not really have anything to do with it.
Also it can be a fine line between having civil discussion and becoming an echo chamber where vigorous disagreement does not occur. Not that my original reply was the finest example of disagreement to grace this site.

Meta: snark does not contribute to civil discussion.
