An important distinction: Expertise is relative, not mastery.
Exploring this: why?
- Social proof and capability from people means you're serving back the community that you were a part of
- People are always hungry for new content, so they look to their peers as well as figures they admire within the space to improve (assuming this is similar to PKM, podcasting, self-development and more)
I have a feeling we now have modern expertise now: specialists in communicating specific skills as opposed to grand 100% knowledge, insight and agility within a field.
Since we are in an era of upskilling in depth and breadth, so does the expansion of expertise and the vague definition of 'experts': which is why a lot of self-proclaimed ones like to flaunt that word over social media to attract the willing.
