Do you think that something as phenomenal as bitcoin in the financial sphere is waiting for us in the future?
Bitcoin is in the financial sphere... and bitcoin is the thing that you have been waiting for. If you are trying to refer to some other nonsense such as defi phoney baloney
then you should be considering that those systems are better built upon bitcoin, to the extent that they are going to be secure.
But why wasn't anything built on top of Bitcoin? I believe it was because the Core developers wanted the blockchain to be as "basic" as possible, and because accommodating them required hard forks. Wasn't that the reason why Vitalik founded Ethereum? Because he can't build the things he wanted on top of Bitcoin?
I am not necessarily talking about short term building or even on-chain building. If the systems are good, then down the road they will somehow be pegged to bitcoin. Right now those very systems are extremely experimental, and it is way more important to get bitcoin's sound money and security correct, first before getting distracted into too many side projects.
I don't have any problem with those various systems getting built and even various experiments in that direction, but it would seem to be too much and too fast to be build a bunch of crazy-ass stuff on bitcoin, when we still only have 1% world adoption and there is plenty use case in the mere sound money challenges and the potential battles that are going to come from that very innovative and never been tried before use cases.
In other words, there has never been any sound money that even approaches bitcoin's, and so it will be quite important and innovative if bitcoin were to be successful in that direction... .. needs a bit of a long view... but no problem if some system like defi shows promise and then gets pegged to bitcoin, but likely more on a second, third or fourth layer rather than potentially introducing bugs into the central sound money mission, which seems to be way more important.
Also, you are not really going to get meaningful defi if you have centralization issues or some dumb bug wipes out a bunch of value, so it seems way more important to get the sound money and security to be quite solidly established. And, we will see with the passage of time, if bitcoin continues with the sound money vision and some of those defi systems end up gravitating to pegging to bitcoin because of bitcoin's security and soundness.
