Anyone thinking on doing these for real?
Understandable to have this opposition, especially as most of the "autonomous killing machine" stories always end up badly. The Terminator, Screamers (based on Phillip K. Dick's "Second Variety"), even the I Robot movie which has 3-law compliant AI.
Notable that in Screamers (and indeed, in "Second Variety" which spawned said movie) the killer bots have a simplified rule consisting in "kill all humans not wearing a tag". The AI gets smart and "improves" into being able to kill humans that wear the tags, thus not only wiping out the enemy, but their makers as well...
