I agree. Why is everyone so hard on everyone else? Look at the outages Anthropic and OpenAI have had. They aren't hiring stupid people but they can't seem to go a week without major platform instability. And you can't even argue that it's because of high load because all of these engineers have worked at Facebook, Meta, etc. They are seasoned veterans that should be able to build resilient systems.
Either they believe their own hype and their reliability is a reflection of the real weaknesses of AI coding, or they're complete liars and doing far more traditional SWE than they claim. I think the former case is far more likely and that while they may have hired plenty of senior people from big companies, there's definitely a self-selection for "true believers" in AI coding baked into that hiring process.
