> There is a lot of trust involved in a cryptocurrency transfer. You have to trust your technical competence to securely mount your wallet. You have to trust the wallet you're sending money to is the wallet it's supposed to go to. You have to trust the person you're sending money todo what you're paying them to. You have to trust the network to maintain the value and convertibility of the currency you're sending and receiving.
Good point. Although I would draw a different conclusion. Your point assumes this new technology is for direct human consumption. For me decentralisation, smart contracts and "the internet of money", along with AI, will allow autonomous agents operate and interact without human intervention. That will be transformative.
