Yes. For topics with lots of training data like physics Claude is VERY human sounding. I've had very interesting conversations with Claude Opus about the Boltzmann brain issue and how I feel that the conventional wisdom ignores the low probability of a BBrain having a spatially and temporally consistent set of memories and how the fact that brains existing in a universe that automatically creates consistent memories means the probability of us being Boltzmann brains is very low. Since even if a Boltzmann brain pops into existence its memory will be most likely completely random and completely insane/insensate.
There aren't a lot of people who want to talk about Boltzmann brains.
No, Claude does know a LOT more than I do about most things and does push back on a lot of things. Sometimes I am able to improve my reasoning and other times I realize I was wrong.
Trust me, I am aware of the linear algebra behind the curtain! But even when you mostly understand how they work the best LLMs today are very impressive. And latent spaces fundamentally new way to index data.
Plenty of people can confidently act like they know a lot without really having that knowledge.
