I remember Rubik's Cubes were popular back in the late 70's. As a high-school kid, I bought a book to learn the patterns required to solve the puzzle, and spent hours mastering the craft. I was a geek even back then.
The whole idea of robotics doing the work of humans isn't anything new. I grew up reading Isaac Asimov and Arthur C. Clark. My grandfather worked for an engineering company that built some of the first manufacturing robots.
Tom Peters brings up something interesting in Re-Imagine! He argues that just like manufacturing jobs have been replaced by robots, Information Work will be replaced by Artificial Intelligence over the next decades. With better systems to measure, analyze, and report business processes, it's not a wonder that many "middle manager" jobs will be unnecessary in the future.
Seeing this Lego robot doing both physical and intellectual tasks really brings home that point to me.
