My favorite commentary on "thinking out of the box with the z axis" is an old Star Trek episode: "Kirk knew that Khan would be back, and asked Spock the most likely direction the attack would come from. Spock had deduced by then that Khan was intelligent but not experienced in space combat - that Khan was thinking in two dimensional terms. Realizing this Kirk had Sulu bring the ship to a full stop, and take the ship down along its Z-axis for 10,000 meters. Kirk also ordered the crew to stand by on photon torpedoes." etc. etc. The point being that we normally think in two dimensions. Ed
I agree that it is an exciting time in the business and technology cycles. We are seeing fascinating riffs on the social networking theme, but I am looking forward to some striking advances in voice I/O and general (machine) intelligence - perhaps initially from the gaming sector.
