If it were true that in 2009 nobody needed the double-spending problem fixed, or that in 2014 nobody needed cryptographically secure state machines with money to execute contractual obligations, or that today anyone needs their transactions encrypted and hidden from AI-powered surveillance bots run by criminals or foreign threat actors, by 2029, it is entirely possible, even probable, that everyone will.
The 2nd and 3rd are pretty huge assumptions. The first is quite possibly the only thing that makes "cryptographic currency" work. The next is that I don't think anyone needs smart contacts. And I think the onerous is to prove they are needed and not just a cool trick. (If I am a bank, I don't care how your fancy multisig works to prevent you from spending while it's in a shared custody escrow account, I want your money in MY account or a Lawyers account full stop).
And the last one I'm not convinced at all that AI is any better at conducting math than we are already with well understood probability equations. That's all probabilistic chain analysis is anyways. Asking chatGPT about basic math seems to validate this.

One day people will stop using "crypto" when they mean bitcoin...

Or bitcoin will exclusively own the term cryptocurrency, as the only currency that embeds cryptographic principles to guarantee its security. As it should be.
