he’s not a “random internet person”, he created Redis. Despite that, I don’t know how authoritative of a figure he is with respect to AI research. He’s definitely a prolific programmer though.

There are plenty of Nobel laureates who well, do rest on their laurels and dive deep into pseudoscience after that.
Accomplishment in one field does not make one an expert, nor even particularly worth listening to, in any other. Certainly it doesn't remove the burden of proof or necessity to make an actual argument based on more then simply insisting something is true.
To be fair, you may find equally capable random people in this thread, doesn't mean they speak with any kind of authority.
