my sister drives a big rig, and my nephew use to do it. Not only is it an extremely cyclical industry, its not for everyone. you have less social life and spend more time sitting than a coder.

One port change can cause truck routes to disappear. also simple routes will probably be replaced by self driving rigs in the future. I would highly not recommend lots of people jumping into that.

however, if this tech rekt lasts, I imagine people will be flocking to the next big thing until that crashes too. its like bulls on ice
