Useful context here is that the author wrote Pi, which is the coding agent framework used by OpenClaw and is one of the most popular open source coding agent frameworks generally.
That's a great shout because I'm sure a lot of people would otherwise just discredit this take as just another anti-ai skeptic. But he probably has more experience working with LLM's and agents than most of us on this site, so his opinion holds more weight than most.
If you were going to dismiss an argument because of who it comes from rather than its content, that is a flaw in your thinking. The argument is correct, or it isn't, no matter who said it.
Your ability to evaluate whether the argument is correct is limited. In theory, the author and the correctness of the argument are unrelated, in practice, the degree of experience the author has with the topic they’re making an argument on does indeed have some correlation with the argument and should influence the attention you give to arguments, especially counterintuitive ones.
