There is no risk, no thrill, no challenge, no thought required. You know where to pick up stuff, you know where you need to dump it. Its almost fully uneventful, and if you are attacked its the same as any other random attack by NPCs. That is why it has become the meta for people: you can just do much more in solo than online. It essentially has reduced powerplay to a game of who can grind the longest, which is why the change is proposed. Its also why I, and many others, gave up on PP; if you dont like mindless challenge-devoid grind, you dont like pp. As for increasing AI: you'll get the same storm as when that happened earlier. Some people just love mindless riskfree grind. That is fine, to each his own. But at some point a choice has to be made, and I am glad FD is considering 'engaging gameplay' over 'mindless grind'.
There's no challenge for the fully A-rated engineered combat ship either, especially as they seemingly don't want to fight each other. Funny how that works eh?
