One of my greatest concerns about this field today is that almost all of the problem discovery happens by a kind of self-interested navel-gazing process, where product builders take the quote “build things you would want to use” a little too literally, and build products for the small niche group of people interested in note-taking tools and processes. This leads to products that seem useful to a small group of other people who are also working in this space and familiar with its vernacular and concepts, but are unusable or unapproachable by most people outside of that small community. I think this is a dangerous failure mode.
