This Arthur C. Clarke-hosted, hourlong documentary airs tonight on many PBS stations. It appears as if the program will be a television version of that excellent book of essays, HAL's Legacy. Essentially, the program is to address the issue of just how far we are from the advent of a computer with the capabilities of HAL-9000. This subject, and the film that inspired it, is a favorite of mine. Dunno if the program will be good or not, but given its PBS pedigree, odds are that it will be well worth your time. Consider it recommended.
