Ask a random nine-year-old to create a Word document. If triviality is your concern, everyone is at some point required to learn Word. It is quite literally one of the first software anyone in the US is introduced to. You are absolutely guaranteed to encounter it at some point K-12 or and in college. Random markdown syntax and git, not so much. The idea that you are going to dictate how you communicate to and share with the rest of your organization (sales, marketing, compliance, legal) because of an affinity for software related tooling is laughable.
