A killer app would prove utility. Something that shows that it has use outside of the ideological and invested. In other words, something that someone on the outside can use. The internet is decentralized and produced "killer apps" that did just that almost immediately. People used the internet and their use of it only increased over time. Cryptocurrency cannot sustain that. DApps are effectively useless. Blockchains are expensive and environmentally destructive merkle trees and do nothing that git couldn't do faster and easier and cheaper. Decentralization has not proven itself to be useful at all to anyone. A killer app doesn't even have to be complicated, it only has to be useful. Nothing about cryptocurrency is useful. It is an ouroboros of busywork and self-justification. So I would ask, why wouldn't a new technology need to demonstrate utility?
