Not sure if its a sufficient explanation, but I like what I've heard from Cal Newport about this. More and more self-service IT systems were able to replace a lot of jobs. But the result is that now you are responsible for doing things via IT systems that were previously outsourced to somebody else. E.g., you're booking your own travel instead of using a travel agent. In some sense, things are more efficient because we don't need travel agents. But also, things are less efficient because now you just have to do this task yourself. Do this across dozens or hundreds of discretely tasks and fields, and you end up with a society where everybody is doing everything themselves in a web browser instead of having some expert or professional to do it for them. So less individual time and focus is spent on your own area of expertise, and more is spent trying to figure out any number of confusing IT systems built to replace a "less efficient" human system.
