A marketer's job is changing very rapidly. Previously, a lot of a marketer's role was in creating things. (Creating ebooks, lead magnets, ads, flyers...) Today, that role is changing to orchestration. We've got a million tools that can build anything at the speed of thought. A marketer's new job is deciding what to build, how to package it, and who to target. The closest analogy would be the role of a conductor orchestrating a live symphony.
