AI or better the "Scripted code for playing stellaris" was always terrible worse.
You find that out easy in any game, where there is a SETTING where this code uses the same rules, as a human without buffs ... and after a short time, it is helpless !
The more complex a game is, the earlier that happens.
So happy to say, that STELLARIS is now a little bit more complex and for sure a better game, as the human player has to plan in advance , what he wants to do !
But because the "zergling" methode to play this game isn't working anymore , that code sucks terrible
Now the devs have to sit down and adapt it to every new possibility they offer human players ... or the code will be worse after every update !
I played before always with a mod , which reduced pop growth down to 20% THAT ALONE was enough that the code failed terrible , even nothing else was changed, because you had to play more strategical and think in advance, because you had to live a long time with your errors ...
so fewer resources , more thinking in advance ! That is now the problem for the "code" runned nations
Really hope the stellaris devs, will be able to handle that, but doubt it
