I think a simpler model is variety.

There are billions of people, you can interview/hire/fire until you get the right match.

There are 2? frontier LLM providers. 5? if you are more generous / ok with more trailing edge.

Everyone thought OpenAI was great, until Claude got better in Q1 and they switched to Anthropic, and then Codex got better and a good chunk moved back to OpenAI.. Seems kind of binary currently.
