I think it is the same category such as mathematicians, doctors, biologists, scientists, sales representatives, marketers, teachers, artists, influencers (yeah, these human influencers) and so on. Of course you can get rid off programmers or mathematicians but then you need to understand and handle stuff on your own. You still need somebody who can check "what's going on". Imagine you are boss. Do you really want to do all things on your own with agents? Sure, let's do it. I think some people can do it but there is a lot of people who prefer somebody else does it for them. You are boss, you know.
