I really don't have high hopes that Elon with do anything crucial for "the rest" (or us)... Even with Twitter, it can be better, and maybe it will be, but in any case, when it comes to decentralization, it's hard to "give up the control"... Those people (in the end, all of us) are thought to control things, and decentralization, blockchain is great to brag, but when you have to make a move than it's hard to do the switch...
When they find a way to control things, they will build it, and implement things... Before that, I doubt...
one maybe good thing that could happen is that they implement crypto into it and fast forward the adoption.
and maybe paying 8$ would get my account shown to more than 10% of my followers :D
