Oh one can identify experts very easily: they are the ones that understand nuances, see and explain things as cost/ratio instead of good/bad and have an up to date view of their ecosystem of choice but are ok with other techs.

The problem is that they are easy to spot only for somebody with experience in the field. This is why companies sometime pay good freelancers to help with hiring: they can assess what the company can't.

And once they do, they realize quickly that:

- there are few experts

- most resumes are bs

- experts are expensive

- they probably don't need them for most tasks and the bs resume dev may be ok, given the price and skill constraints

- they had one expert internally all along, doing half the job of the rest of the entire team and they should make sure this expert stays

Maybe experts don't call them selves experts.

I have a friend that had some home remodeling work done, poorly. The friend said to me, "But, they were professionals!" I responded, "Well, that's the problem. A professional is someone who will do the least amount of work in the least amount of time for the most amount of money. If you want someone who actually cares about the work, hire a craftsman instead of a professional."

Well, it is said that a wise man never calls himself a sage. Others do.

Yeah, this expert prefers Guru. /s
