Yes, in retrospect Go's push to "make concurrency easy" ended up being one of its worst attributes; Go's real value is in its simplicity, efficiency, and boringness, all of which concurrency runs counter to. On the other

Basically, yeah, although "insecure" is a bit too broad; unauthenticated encryption is insecure in some contexts, like sending messages to another person. But if you're encrypting your own backups, and all you care about is

Weird. That doesn't make any sense to me. btw, the whitepaper probably used "number of leading zeros" because that's what Hashcash does.
