Well I (and many others) see Linux as a fragmented and also the reason why it's behind the other operating systems. That's the trade off really. You provide many options.. and only attract enthusiasts. Keep it locked and under a tight format and you attract the masses which consume it and don't care to know the system.
That's where crypto/blockchain is really.
I agree that the right base is here in blockchian and then agree that the struggle is real. That's why essentially the issues isn't the on-boarding, it's actually producing that which those whitepapers and teams promised. Too many were trying to get to the green in one hit when the trees weren't cleared yet.
2026 - I prophecize greatness for blockchain.
Maybe sooner?? but the world doesn't look like it's in a state of progress currently. It might be that nation states get into a tussle for digital supremacy soon and we go through a type of "digital darkages." Then when we emerge out of it these new decentralised systems likely winners.. as you've made point about before.
