Aside from what @tromp said, IIRC allows faster QC brute-force collision attack on SHA-256 which reduce 2^256 range into 2^128 due to something called Grover style speedup.

Like If We Train Specific AI MODEL to guess these Seed Phrase

By default, i would treat it as "snake oil". There are other real and more reliable ways to guess BIP39 seed phrase, such as finding out weak RNG used by one of Bitcoin wallets.

Thanks for making it simple @tromp @ABCbits
That part about the quantum computers having only Quadratic advantage that was superb 🤯

So if I got that right Even a super powerful like quantum computer wouldn't be able to do the bruteforce a seed phrase & even with Grover’s algorithm speeding things up anytime soon gotcha

but what about the wallets that is using these weak RNG or even bad entropy back in the day? So Should people we worry more about that than quantum threats?
And just curious do you think that the post Quantum crypto wallet will ever become a mainstream ?
