So what turns a controlled environment into a chaotic environment?
Honestly, don't know. Maybe mathematicians do, but I imagine it's a philosophical question. The only agreed upon thing would be that significant varied complexity is what is needed to be determined a chaotic environment, philosophically. How significant would be the disagreement.
And what is the problem with a patterned outcome? Intelligence was still used, so what do the results matter?
Well, we're still trying to determine exactly, precisely is "intelligence". But ChatGPT is definitely not intelligent, that I do know. I think Google really helped elucidate that point recently to Americans.
The problem with this is than an all loving, omni-benevolent being not just has love for all, but maximal love for all, which contradicts the notion of willingly allowing suffering to exist in any form.
Again, that depends what kind of "maximal" love. You have maximal love for your parents for example (assuming you had good parents), but that's definitely not the same as romantic maximal love.
If there's a God and they created everything, well, I assume the "maximal love" would be akin to a human creating something and loving that creation. Considering the massive difference between an omnipotent being and a mortal human, I'm hesitant to even say it's similar to a human and self aware robot.
