This does not surprise me at all.
AI decision-making suffers from the same flaw as consensus decision-making or “groupthink”: there is a built-in bias against creative thinking - thinking “outside the box”.
There are leaders and followers. Most would agree that the most creative thinkers are not the followers. Yet, a consensus is formed when an idea garners the most followers.
I think AI is ultimately process wherein consensus thinking is sped up - and therefore does not produce the best ideas/solutions.
AI is plagiarism in the rear-view mirror.
Literally.
