What's described is true, but managers in a lot of industries want drones as described. Lawyers and engineers have some extra status in most industries that have forced managers and owners to share a little power and a little wealth with them. The managerial class will take any opportunity to claw back any power and wealth they can, from any workers. That's the appeal of "AI" isn't it? Access to expertise without paying people money, or giving them power, and certainly not creating another class of worker with some autonomy.
