Quantum Proof soft fork progress

Just wondering if there’s any recent updates on the progress of soft forking bitcoin to have post-quantum cryptography to guard against quantum hacking. We saw how fast AI advancements came upon us, and I suspect quantum computing will do something similar soon. I’m wondering how protected bitcoin is against this.

Also, due to UTXO I’m aware that all previous transactions must remain valid during a fork, so satoshis crypto will remain valid — is that true?

Thanks.
