Also, the assumption that the laser is for destruction may be false. What is the laser tags or scans blue objects? Maybe for a space probe, or a scan on enemy robots? What if the robot makes the assumption that the laser is for destruction when it's not, or vise-versa? Does it really matter, when it is programmed to do it anyway? What if the AI is destroying, or thinks it's destroying fellow robots? What if it does not want to? Maybe this is an example of religion from assumption? Because it is 'destroying' blue things, it assumes that is it's purpose. Behavior/motivation from assumption...

This was very interesting, thanks for sharing. My first reply on-site (for a while at least), hope it wasn't in too much of a different direction from what you meant.
