That does sound like an interesting video, and I'd like to see it if you find it (or I might search for it later).

As for the Star Trek (TNG) interpretation of AGI, I suspect something like this in the real world would give rise to a kind of "oracle" situation, which creates its own dangerous problems. A system which functions as described only by observing and giving input where asked still has the potential to affect the outcome of events simply by being a reliable predictor.

A paper explaining this concept far better than I would be able to in a HN comment is available here: http://www.aleph.se/papers/oracleAI.pdf
