I used to hate the idea of becoming an expert and rebel at all those who suggested i focus and become an expert.
I used to hate and rebel it so much so that i have let it dictate the course of my career so far.
At this point i find that, it has it’s uses.
1.Claiming/accumulating credentials/certifications/work experience for expertise in one area,
creates an easy,packageable brand of your skill sets.
In fact that is what most modern educational institutions are about. As for whether it’s good or bad, i don’t know.
2.A clear, surer, certain path can be created unless of course you are claiming expertise in a completely new area.
(think Mandelbrot* and fractals or script-based thinking(EY) or narrative based decisions(VGRao) with a preset narrative or script)
3. It can create anti-fragile careers, as long as the branch is established and you manage to convince a majority to acknowledge your accreditations.
* — Am aware of that it’s disputable(only among mathematicians?) to say Mandelbrot created the area,
but i don’t know the history, and just need a reasonably well-known example/analogy here.
On the Other hand, generalist requires a hell of a lot of effort and most importantly,
the skillsets and/or accomplishments that come with it are not scalable across multiple humans and their belief/trust/faith**.
** — whatever that convinces them to part with their money for using your help/advice/service.
