the premise seems a bit faulty to me. why should we be giving next token predictors access to spend our money? like what great benefit do we get from this that we should allow them unfettered access, but with safeguards in the form of hard budget caps?

I don't think Simon means you should hand off the spending to agents/LLM (which would also make me uneasy) but that if you're probing one for hosting/SaaS providers they should default to recommending ones with budget caps
