The problem with cryptocurrency is that it builds cost right into the protocol, and social effects seem to kick out cost-free protocols(BitTorrent is doing great, but nowhere near the hype level of BitCoin, and there are very few non-coin P2P projects with traction now). Instead of becoming too cheap to meter, it will always cost something. It can never really be suited for a heavily partitioned network if it needs consensus. That's a very scary thing. If we are going to build the future of tech, it should be resilient. If a building's internet goes down, I should still be able to get a message from one floor to another. It also imposes another kind of cost. Irreversibility. Our current ecosystem is based on being able to fix our mistakes. Banks reverse transactions. We can delete unwanted social media posts from when we were 16 and wanted to be shot because of hair loss. We can't do that with a ledger. Which means our current level of security is unacceptable. A large percentage of people might have lost their life savings if everything was crypto. Even things like a bad autocorrect algorithm could cause a permanent embarassing entry in the blockchain. I would not be happy if someone grabbed my phone, teabagged the camera, and anyone with some special "View hidden posts" tool could see it forever. That's what I'd call sub optimal UX. Hardware wallets are no solution. They can be lost, and impose a tax on our time. I don't want the future of tech to have high cost built in, whether that be time, money, or safety. There may be uses for it, but we should stop baking it into decentralized protocols, and stop promoting it as a full replacement for fiat unless you can guarantee 100% parity, every bit as stable, every bit as easy to prosecute fraud, etc.
