Who are these people who say "never"? Why be a robot refusenik? Keep in mind that a good two-stage snowblower will easily set you back at least $700 or $800. The only thing you can get for $500 is a single-stage snow-thrower, which is basically useless anywhere north of Interstate 70.
The moral of the story: Robots are coming for some of our jobs -- and we should be happy to turn over some of the lousiest tasks, like clearing the driveway.
