@Rocket cold fusion has been "right around the corner" for longer than everyone reading this has been alive.

Robots doing tasks like lawn mowing is conceptionally no different than having a service do it. Robots are also going to be a much worse version than a human doing it, if robot vacuums is any indication.

Robot vacuums is less of a change than a dish washing machine, simply because the amount of time it frees up.

Any type of computing advancement needs a technology that uses it. This is why we have phones that take way better video than 10 years ago and .. it's kind of like "ok, woo, whatever, this video is in 4k rather than 768 .. "
