Eg. how far away are we from having remote-controlled tractors and combine-harvesters? Sure, get them home into a garage when they need servicing.
Hospitality? There are places which, especially in the first pandemic year, have gone all hands-off (eg. get a token to access a property on your check-in without talking to anyone).
But rather than can we, I think the point should be should we? There's a psychological cost to working with people you've never met personally, never hanged around with... And some people will struggle to get any social activity happening in their lives without work.
I've worked remotely for 15+ years, but I don't think it's for everybody, or for anybody all the time.
