Totally agree that current generation cryptos are all doomed, but the problems can be fixed if we see some real innovation in alts. There is the possibility of making our own decentralised global identity system.
But this possibility seems pretty scary to me. I'm supposed to put my global idenity into some sort of decentralized information network. I worry about things like: what if this network is overthrown, who is organizing it? More importantly, what if the information in this network is used against me? Ie, people with X, Y, or Z characteristics are deemed unworth to A, B or C.
I'm not saying such a thing won't come to pass, I just don't see it in our lifetimes. Who knows, maybe in some future generations though.
