The entire post is one big ad hominem. The entire premise is "these people's arguments don't matter because of who they are", which is a fallacy.

I don't care if you think that a broken clock is right twice a day, that competent, intelligent people aren't wrong all the time, or that people are sometimes able to look past their biases and call out the truth, but dismissing arguments for or against AI just because of who someone gets a paycheck from is wrong.

Not the most gracious post, I suppose.
