Perhaps the peer-to-peer work behind "crypto" survive. From what I have seen it is relatively easy to run a node on the Lightning Network for example. Direct connectivity, e.g, via a peer-to-peer overlay network, to other internet users, free from "tech" company middlemen, does not have to be used for financial gain let alone illicit activity. There are many possibilities. The original internet was intended to be peer-to-peer. When I first read the Satoshi paper it seemed that was the intent behind Bitcoin as well. No middlemen.
