As an Amiga romantic, I’d say we have no illusions about a late-80s Amiga being a good idea if it existed today. But it captured my imagination (and at just the right age) like nothing else.
Without those people lots of history (and hence knowledge) would be lost. I’m happy they are around.
All of those are systems small enough that all their details could fit inside one human brain. That is a very intoxicating feeling, at least for me.
