I think the more concerning error GP makes is how he makes deductions on fundamental nature of the intelligence of LLMs by looking at "bugs" in current iterations of LLMs. It's like looking at a child struggling to learn how to spell, and making broad claims like "look at the mistakes this child made, humans will never attain any __real__ intelligence!"
So yeah at this point I'm often pessimistic whether humans have "real" intelligence or not. Pretty sure LLMs can spot the logical mistakes in his claims easily.
