The transition won't be good for people who currently drive semi-trucks or who aspire to. However, there are some reasons that this may actually take a bit longer to fully play out than it appears. To start, there is the transition time from existing capital stock of trucks (those things are hundreds of thousands of dollars); there are also many activities that drivers do that aren't just driving- delivery drivers are often responsible for stocking and displaying the goods they bring; there are various paperwork issues that drivers deal with; there is the care and feeding of these large complex machines in often austere circumstances. I imagine you'll see a lot of hybridization of activities before (or if) you see the elimination of the human- such as a human riding "shotgun" and dealing with any issues or activities that arise when the truck is stopped, or where you see more humans employed in servicing and response roles. That being said, hauling shipping containers around the port of long beach is probably on its way out. I feel for those drivers.
