Won't take any fun away - there'll be a crowd of people who try to use it to make a hole in a workpiece and then watch it drive itself into the hole...

But it's an interesting idea. Not sure how practical it will be. We don't see much of that other idea that came out a couple of years ago - a hand-held router with a built-in correction facility. You moved the router roughly where you wanted it to cut, and its on-board positioning system "corrected" the cutter position to get an exact cut. Again, an interesting concept, and who knows if someone can turn it into a practical machine. Where would we be without people exploring new angles? I bet there were a lot of people who said that the whole idea of fused-filament 3D printing was never going to fly...
