When it comes to current hardware then it can be said that Bitcoin is highly secure but surely in future developers might need to add more security options for Bitcoin holders because in next few years we might see quantum computers and for such computers it won't be much hard to brute force the current security system of Bitcoin.

Prevention is better than cure might apply here, I know at this time there's no such security threat to Bitcoin and that 51% attack is not going to happen either thanks to all miners.

However, in future there're some risks when it comes to current security algorithms. SHA-256 is indeed quite secure as of now but who know in next few years it might not be that much secure.

A few years ago it wasn't possible to create videos with AI video generators, only those who had skills of cinematography could make good videos but now AI video generators like VEO 3 can create some good quality videos with just a few words of prompting.

World is moving fast, I know the example of AI video generation is somehow off topic, but it's still true that such a thing was not present in 2022 or before that or even in 2023.
