I might be a crypto noob, but as per my limited knowledge I don't see how BTC can become a usable large scale currency. The transaction rate on chain is too low for real world use cases. Off chain you can use things like lightning, but lighting either requires you to open separate channel (which needs to be on the blockchain, thus will run into the same transaction rate issue), or keep one channel open with some entity, and make all your transactions flow via that entity (kind of a bank, but with no real world protections whatsoever). Not to mention the total irreversibility which makes it much harder for normal people to use.

There are several other issues as well with crypto, and I don't see how is it going to become an "irrevocable disruption".

IMO the transaction rate is too low because the gas fees are crazy high. This is why we need actual proof-of-stake (not ETH 2.0). EOS is the first project to try an tackle this. From what I can tell, it scaled. Transactions remained fractions of a cent. EOS got caught in morality of consensus (e.g., under what conditions to reverse, how to handle disputes). However, it looks like AI can improve on this which is both terrifying and exciting.

Irrevocable disruption to the US could simply be enough countries move off the US dollar. To do that a new currency would be created/adopted. BTC serves as proof-of-concept that value is driven by sustained adoption and trade. Further, the level of sustained attacks crypto has undergone from countries such as US and China reflect the disruption crypto, as a decentralized security, has on the world economy. All this to say, it's quite possible.
