> 1. Plumber is a skilled trade, but the "skilled" parts will eventually be replaced with 'smart' tools. You'll still need to hire a minimum wage person to actually go into each unique home and find the plumbing, but the tools will do all the work and will not require an expensive tradesman's skills to work. I'm not a plumber, but my background knowledge was that pipes can be really diverse and it could take different tools and strategies to fix the same problem for different pipes, right? My thought was that "robotic plumber" would be impossible for the same reasons it's hard to make a robot that can make a sandwich in any type of house. But even with a human worker that uses advanced robotic tools, I would think some amount of baseline knowledge of pipes would always be necessary for the reasons I outlined. > 2. Waiter serving food, already being replaced with kiosks, and quite a bit of the "back of the house" cooking areas are already automated. It will only take a slow cultural shift towards ordering food through technology-at-the-table, and robots wheeling your food out to you. We've already accepted kiosks in fast food and self-checkout in grocery stores. Waiters are going bye-bye. That's true. I forgot about fast-food kiosks. And the other person showed me a link to some robotic waiters, which I didn't know about. Seems kind of depressing, but you're right. > 3. Shelf restocking, very easy to imagine automating this with robotics. Picking a product and packing it into a destination will be solved very soon, and there are probably hundreds of companies working on the problem. The way I imagine it, to automate it, you'd have to have some sort of 3D design software to choose where all the items would go, and customize it in the case of those special display stands for certain products, and then choose where in the backroom or something for it to move the products to, and all that doesn't seem to save much labor over just doing it yourself, except the physical labor component. Maybe I just lack imagination.
