As long as there has been organized work, there has been supervisors. The often hated individuals who often make sure that the work is done under spec, and on-time. The ones that are “responsible” for production, for hitting the quota, for making the numbers.
Each worker may have their own idea of what to do, how to do it, and when to do it, but the result has to be there, whether you’re building a product or delivering a service. This where the super justifies their salary. So, if there are workers, you can expect to have supervisors.
But what happens when the workers are robots, or AIs? I say you can be dang sure that there will be someone overlooking them. That’s the future of the Middle Manager, all the same skills, except for the interpersonal ones.
Strange times.
