I'm already thinking way beyond this, what if super computer comes ?

A complete disaster it will be, trust me...
you are talking about QC, right?
By the way, there's really some evidence that AI could be used for hacking, and these traditional hackers mentioned are also adopting the use of AI. so it's not really about who is the bigger threat since hackers are people and AI is a system that they can use to their advantage.
If you are familiar with the
Gamdom hack, where the casino lost over $3 million, i know it's not totally related to Bitcoin wallets, but i just use it as a reference to show how vulnerable online systems can be. Although there's no confirmation that AI was used in that attack, AI could be a big help to hackers in finding vulnerabilities.
