I get that, but a dozer or hoe costs a bit more than a trench compactor, and is gonna be used in different situations. And that's not how that technology will be implemented, sure it'll start for dangerous stuff and then foreign countries, and then before you know it you are working under a robot being driven by a dude in Texas (and then likely overseas) factory for 10 bucks an hour, all connected with a cell phone. Operators have a hard enough job when they're right there and are extremely skilled and qualified, not to mention the fact that he's right there with us when shit hits the fan.
