Reasoning is actually pretty good now. An AI can compose a sonnet on electron degeneracy pressure no-problem but ask it where the red ball is - and really inspect its localization of that red ball and it’s way off. Orders of magnitude of imprecision.
A modern AI can reason through the trolley problem and millions of variants. But it can’t see the person on the track with very high confidence, or be sure that the trolley is going to hit the person or not.
