AI are skilled, but brainless. New players have brains (in theory), but are unskilled. In theory you can teach them basic skills to put them on par with AI, but that takes time and a ship that's both forgiving of mistakes and one the pilot is willing to fly.
Of the ships that have especially unforgiving roles, 3 of them can have AI fill in the gaps effectively (doesn't take a ton of micromanagement): Pyramidion, Goldfish, Squid.
2 of them, Spire and Mobula, absolutely cannot. Some might argue Galleon should go here as well, though I think otherwise.
Having more ships that people would actually want to fly whose more unforgiving roles can be filled adequately with AI would do a lot to encourage pilots to fly ships that they wouldn't normally take with randoms. Very new, very inexperienced people are not capable of filling the unforgiving roles, so we need the AI to make up for that if you want to see experienced captains taking newbies on ships that aren't Pyramidion.
