I absolutely don't think a sentient artificial intelligence is going to wage war against the human species.

Right now, I think robots are where it's at. And yes, I'm biased. Robots and space, because with home rocket kits and Lego Mindstorm sets, people can get involved. I was raised on Transformers and GoBots, so I can't imagine what kids who are building real robots are dreaming about.

A robot-arm in a factory doesn't decide minute by minute whether to rivet or revolt - it just does the job is has literally been trained to do. It's if and when we build a conscious robot that we may have to worry.

Each new generation builds on the work of the previous one, gaining new perspective. New verbs are introduced. We Google strange and dangerous places. We tweet mindlessly to the cosmos. We Facebook our own grandmothers. I, for one, don't want to be left behind.
