Actually, and even by this mass adoption for cryptocurrencies, i think it's somehow similar to the Amazon at its early days with the same number of users actually crypto has, as described in the second Tweet mentioned in OP .
And I would probably substitute "blockchain" for "decentralization movement". A blockchain can be centralized and be nothing more but a database with a single point of failure. What we are seeing now is decentralization as it was never achievable before. True decentralization means that actually there is nobody who can shut a system down. Obviously, Bitcoin accomplishes that.
It is similar to the early Internet in the sense that the potential for technological transformation inherent in Blockchain might be comparable to the transformational power of the Internet itself. I guess that is what people mean when they say it.
Indeed, there are lots of potential that this new system will continue to evolve and recieved more acceptance all over the world,
same thing with how internet gain its success before.
Most people see that and will continue to support whatever they understand about this new progressive system.
