@Logicfest -- such a system probably wouldn't work but not because the computer couldn't reach the intuitive decisions you mentioned. It would fail because it didn't have enough information. Every case has different circumstances and it would be well nigh impossible for a DSS to have access to each possible circumstance.
Regardless, the discussion is somewhat moot at this point. These things are developing but they've not gotten to the point where they can access enough information and consider enough scenarios to reliably come up with correct answers.
