Also a quick ai search says that the broader industry is not quantum resistant. But maybe you know something that it doesn’t. It said they use RSA and ECC. Wouldn’t bitcoin just need to go from SHA256 to say SHA512, SHA1024. I am probably being naive especially since I know very little about cryptography.

For Bitcoin, it's not SHA256, it's secp256k1. (The near-term threat from quantum is to the wallet keys.) You have to move all wallet keys to a type such as Falcon.

Or keep your pubkeys secret. No address reuse, native segwit. The mempool time is a threat vector, but you'd need a REALLY fast quantum computer to snipe those assuming they pay competitive fees.

That said solving the mempool issue with an optional address type to shut down the FUD would be nice even if I do believe it's a non-issue for decades if not longer.

It's wild that people can see Jamie Dimon buying and assume that he just must have overlooked the quantum threat which they're smart enough to give accurate risk value to. The hubris is palpable.
