We can be sure of is that the blockchain came to stay, of that there is no doubt. Now if it will be bitcoin or another alt the main currency in the future, I think the maximalists are wrong, the bitcoin is the precursor of the crypts and has fulfilled its function but have come out other projects with considerable improvements, in my opinion currencies like ethereum that allow smart contracts where each company can create tokens backed by the same network have a great future .
I share your thinking, being bitcoin maximalist goes against the same concept of bitcoin.
