Merry Maids are generations away from being replaced by technology. You can have an automated floor cleaner in a large structure like a casino or airport, but they will go in circles if there are people they might collide with. There is no technology presently available that can park a car, enter a house, climb a set of stairs, and clean a bathroom.

Is there a robot that can do home health care services, or daycare? Who would entrust an elderly parent or a toddler to a robot? There are robots that can serve food and beverages, but people have been getting food and drinks out of machines for a hundred years. They want a person to serve them.

I have been watching autonomous cars with engineers riding in them for ten years here in Pittsburgh. They work great, but I have a feeling they're not going to happen simply because so many people drive for a living. They don't need any more research, but lawyers are standing by to sue any company that manufactures one that is in accident. When are drones going to deliver packages and take-out? I thought that was going to happen ages ago. Where can you find a robot to change your oil? It's the simplest service on a car.

I do plumbing as part of my work duties, and on the properties I manage are plumbing fixtures that date from the 1940s up to very recent no touch fixtures. The old faucets, sinks, and commodes are well built, beautiful, and most of them still work great with standard plumbing parts. The new stuff constantly needs batteries and regularly has stoppages because they are more complicated. They won't last as long as the old stuff because they have more plastic, and then a person will have to fix them so I will work as long as I like.

Go to a construction site and you will still see a bunch of husky guys there because a human can do so many more things than any robot that has ever been developed can do, like climbing ladders, shimmying down holes, unloading a truck, and running a host of different tools. There are still people on oil platforms and working on farms, just fewer. If people want to do worky work there will always be something for someone who isn't afraid to get their hands dirty. Assuming that every job will be replaced by automation is wrong.
