>CNC machines always have an operator next to it, did they remove the machinist? NOPE Certainly, I agree. However I've seen machinists running 3 machines at the same time. CNC machines can be programmed to run automatically for "runs" of parts e.g. through-feed lathes which can make hundreds of parts in a row. An operator is needed to set up and verify the first few parts, however after this is verified, the CNC lathe can be set to run for hundreds of parts. There may be a need to clean coolant, or change tools, but most CNC lathes can do this anyway. Trucks will need to get loaded and guided by professionals, but for long, cross-country routes, most of the driving could be done remotely by an operator who presides over several trucks from the central hub. There may be a need for a manual driver to drive the last 10% from a local truck hub, but I think the more mundane, highway driving can be done by computer. Going back to CNC machines, toolpaths are now automated for the most part too. Based on the cutting bit, material, and machine, and coolant, the machine will develop it's own optimal adaptive toolpathing. There still needs to be input from a human, but not nearly to the extent that was needed 20-30 years ago. My point is that there will always be advances in guidance and optimizations of mundane labor. That's the nature of computers in general. Given that we already have self-driving/guiding cars, i.e. Tesla Lane Guide, it makes sense that people will work hard at pushing this further.
