I can kind of relate to that.
I wouldn't call myself a professional bullshitter, and I wouldn't still have a business after ten years if I didn't have substantive knowledge of what I do.
However, my cultural and family background is in the humanities. I spent most of my adolescence and teenage years on my programming hobby, like many people here I think, but the route to a tech career was a rather incidental one. My parents are philosophy professors, and I entered university with a political science major (switched to philosophy), before dropping out two and a half years later to pursue what was by then an ascendant tech career.
The discord between my background and the psychology of typical software engineers and business guys has led to amusing, sometimes infuriating cultural clashes over the years.
Nevertheless, I've got the comment more than a handful of times over the years that I really should have been a writer or do something involving lots of speaking. You can probably tell from this comment alone that I'm not a person of few words. As I get older, this has seen me enlisted to assist with marketing copy, résumé polishing, LinkedIn profile formulation, and a variety of other tasks that require putting a spin on things and drawing on one's facility of rhetoric. Some have said I'm a lawyer on the inside, combining the logical, left-brained, procedural qualities of a programmer with a knack for wordsmithing eloquent pleadings.
It's a weird space to dwell in. The real nerds think I'm a bullshitter half the time. The real bullshitters think I'm a nerd who lacks the social jujitsu to really hobnob with Visionaries like themselves. Beats me.
