>It's broken! A partially broken process is no solid foundation to build others on. And while there are some exceptions, an unreliable tool/agent is often worse than none at all.

Are humans broken ? Because our reasoning is a very broken process. You say it's no solid foundation ? Take a look around you. This broken processor is the foundation of society and the conveniences you take for granted.

The vast vast majority of human history, there wasn't anything even remotely resembling a non-broken general reasoner. And you know the funny thing ? There still isn't. When people like you say LLMs don't reason, they hold them to a standard that doesn't exist. Where is this non-broken general reasoner in anywhere but fiction and your own imagination?

>And while there are some exceptions, an unreliable tool/agent is often worse than none at all.

Since you are clearly meaning unreliable to be 'makes no mistake/is not broken' then no human is a reliable agent. Clearly, the real exception is when an unreliable agent is worse than nothing at all.
