Depending on how you count them, I've had around 8 different jobs in my career, and I was almost always underutilized and often had more downtime than work to do, which of course also made me expendable, of course. Part of the problem is that not many people necessarily understood my role as an analyst, anyway. I suppose the ironic part is that in some of my jobs, my responsibilities included making systems and processes more efficient, if not automated. I would think the aftermath of this pandemic will help companies realize how much more efficient and productive they can be, though. Over the past year I've finally been meeting the right entrepreneurs to work with to be done with the corporate world, and the clean energy space should rebound faster than many others.
As for Amtrak, a major problem they have is that freight lines own and have priority on a lot of the tracks. For better or worse, self-driving vehicles will probably effectively replace most trains once they're widely deployed. I still like the idea of the hyperloop, too, but I just don't think it will be cost-effective.
