Not completely. It just means you can have an AI do the useless busywork instead of a human. Something can be economically useful but still have proponents in a firm.

A lot of the "useless work" is busywork you do being a part of an executive's empire so they can claim they managed X number of people.

How can it do that?

Call your project Gas Town, write a blog about it, and investors will be swarming all over it thinking managing agents is even more impressive than managing people.
