My node is fully optimized without AI and I would consider my node to be among the ones that have the highest throughput and decent routing earnings. AI is useful if you have no clue, but otherwise it is just burning ressources for something that can be applied algorithmically.
Obviously, without mentioning AI, no investor cares. I understand that game. But you still have "blockchain". Maybe that is something worth still 😉
But get yourself some land. Plant lots of trees and let the soil recover. Did this and it is surprisingly fast how everything fixes itself if you let nature do its job.
What you can’t fix is obviously the water and air as it highly depends on what happens around you.
