I’m with you in the long term.
I am curious what kernel is backing the computers on the stuff SpaceX is doing. I’ve never seen their consoles but I am guessing we are closer to modern reusable hardware and software than we were before. When niche applications like that keep getting more diverse, i bet we will get more open specifications so everything can work together.
But again I am more pessimistic and think 50 years would be relatively early for something like that.
We solved this like a year ago! Though I had completely forgotten what it actually was.
