Spring is upon us and there's nothing like the smell of fresh grass clippings misted with the blood and brain matter of the neighbor's cat. These lawn mowing robots, which do not know the difference between a stick and a wee kitty sunning herself near the rose bush, are entirely autonomous and cost about $1500.

I think the most important lesson we'll have learned from these things—after we drop even more exercise from our lifestyles, become huge waddling blobs, and these robots turn on us—is that robots and mulchers don't mix. I mean what's the Scooba going to do if it becomes self-aware? Pee on us?
