Mainframes have nothing to do with this.

RISCV is still just a computer - would work just fine on a logical level. Raw compute would be an issue with today’s hardware.

It does sound a bit like creating plausible deniability for some sketchy transactions later on.

Mostly agree. Audiobooks are not my thing, but of it were - I’d look for a way to resume where I left off, maybe some recommendation on what to listen to next.

In general - once you’re into hosting stuff and past the initial barrier of setting everything up - adding another service is dead simple.
