Not OP but I feel compelled to reply.

It's indisputable (borderline tautological) that specialization trades breadth for depth. This (obviously?) implies the risk of targeting a narrower market, and the upside of being more attractive to that smaller population. It's a typical "quality over quantity" tradeoff.

To say there's no "sliver of truth" in pointing that out (let alone w/ an unwarranted jab about projecting fears) is... strange and maybe hypocritical. TLDR your response came across as emotional and passive-aggressive, and confusing.

I do not necessarily agree with this as stated. A specialist will have access to many roles within their speciality that are not open to a generalist. The market for generalists without deep expertise is also extremely crowded.
