"Top talent" - I'm curious, do you really believe this is a normal / proper / desirable way of talking about other people?
Yes. Highly accountable and responsible people with deep knowledge are rare.
It is logical that there are people who are great at what they do and others who are not. We’ve all worked with both and if you are in the business of finding talented people, how else would you talk about it?
I'm not OP but I think it is both normal, proper, and desirable.
... What are you getting at, I'm genuinely curious? What's wrong with the phrase "top talent"!?
Sounds a bit like casting lingo in performing arts, but other than that, not sure what you're hinting at.
