I don’t know if AI is technically better it’s just different and doesn’t play like a human. Humans hate lossing pieces but AI doesn’t care as long as the outcome is a win.
AI absolutely plays like a human as it’s trained by humans. The only difference is, AI will do the most optimal move, while humans might hesitate. That’s also the reason why it’s bad to put AI into fighter or bomber jets. The AI has a clear goal but a human might struggle to fire at an unknown target. Because the human has to life with the consequences.
