Bitcoin is a decentralized, peer to peer, currency. Not a centralized, third party, investment vehicle, which is sadly what it is turning in to.
I have the same attitude as you, but if you just take this forum and its active user base, I believe most have never used Bitcoin as a currency and consider it just a tool that will allow them to one day have more fiat than they used to have. Maybe that's why the world's elite is somewhat
mild in their attitudes towards Bitcoin, if we take into account that most coins will still end up where they can control them.
In 10 years from now people may spend Satoshi or sub-units of that. Bitcoin can still function as a currency, the 8 digits after the decimal point is a lot.
It all depends whether people will still spend or will be convinced to just HODL.
I have no doubt that there will always be enthusiasts who will try to follow Satoshi Nakamoto’s idea, but I think there will be far fewer of them in the future than there are today. Most people still have their exit point, so I've already written that with price increases, coin ownership will change in favor of wealthy individuals, companies, funds, central banks, to the point where the average Joe will no longer have anything in his crypto wallet, and the price will be so high that he may not be able to afford to buy even 1000 sats.
