Interestingly, I asked this question to AI and it contradicted itself on several points. To be fair, I wasn't specific enough regarding majority node control (which is what I was really asking). So in fairness, AI does sometimes help me learn how to ask better questions. I do agree with that. My human brain just understands that would be majority given the current numbers.
But asking it about majority control gave an answer that is 100% slanted toward an attack vector (if that was the goal, but it could be regardless). Like it would be game over. But is that true? That isn't something I'm finding AI is imaginative enough to speculate on. At least not the models I've asked. Even the couple benefits it gave are still bad for the average pleb.
So I'm kind of back where I started. Running my own node still seems important, but how important is it if someone can just out node me and everyone else?
