plz dont forget that PoW technology uses utter energy and is not sustainable by any means; therefore completely useless for modern world transactions on a large global scale.
there are fast and sustainable models used today and in the future and i know you know it cuz u are smart

I think your just tossing out random challenges as they come into your head without thinking much about them.
Blockchain technology adoption is growing at about as fast a rate as could be reasonably imagined. Just because it hasn't turned up in your local supermarket yet doesn't mean that that isn't the case.
Secondly, in terms of potential social impact, Bitcoin is probably the biggest single invention since penicillin. That may sound over the top - I don't think it is. Over the last 30 years, a revolution has taken place in terms of migrating the world's trade from paper to electronic networks. Every single one of the millions of trades that occur each day has to be managed by a counterparty, thus incurring associated fees, transaction delay and counterparty risk.
The fact that a technology now exists to eliminate all counter parties from the equation is bound to have a huge impact. CLearly, adoption has to reach a critical mass before that impact is substantially felt, but that it will do so is beyond doubt even amongst the most conservative of commentators.
