Klaus Wuestefeld is most famous for Prevayler (2003), the earliest implementation of event sourcing that I came across.
His ideas around p2p sovereign computing where intellectually dishonest though. Everyone wants sovereign computing, that's a no-brainer, but scalable decentralization is a hard problem that nostr too hasn't solved yet (the scalable part).
It's like coming up with "world peace" as a great idea. No shit. We all want world peace. But it's the how that's kind of hard. I'm doer, the self-proclaimed visionaries out there can take their "great ideas" and stick them somewhere.
