Many faults with this argument.

1. You don't need to be an expert in domain A to comment on that domain, this is credentialism that AI itself is dissolving

2. the fact that your non-technical friends can vibe code this much itself is a proof of (1)

3. the proof that Anthropic didn't find important linux bugs is strange when they did find small vulnvs that could be chained to create real exploits - that's how most attacks were made in the past

4. OpenAI recently dropped 400 proofs solving some of the most important problems in mathematics without any expert in those fields which is a great counter example to you
