What's with all these questions?
Is AI definable? If so what is it?
What do you mean here?
Also, my ICT Teacher was talking about AI's before school let out and he said that it will start to become a possibility when our processor speeds start reaching as high as 10GHz.
Well the IBM Roadrunner, is runnin at 1PetaFlop. so it could probably have AI, like in T3. Terminator: "SkyNet is now self-aware, it will launch a nuclear attack to destroy its enemy in 1 hour and 46 minutes."
But if you want to see some simple AI, because proccessor speed is not really were AI will start, AI depends upon how the program is wrote, by what kind of althithograms its uses(srry for my spelling), my Lego Mindstorms robot, learns how to sort bricks through trial and error, and its proccessor speed is about 8MHz so i has a simple AI but without the speed like the Roadrunner.
You can see the video of my Learning Brick Sorter in action at youtube, here:
