I would rephrase it to: you need people great in tasks that you actually needs them to do.

Great technical star probably don't know AI algorithms and may ressent having to implement math based routins with little tech knowledge being needed.

Someone who is great in algorithms might not be best for tasks heavy on configuration. Someone who constantly seeks new might have trouble to perform routine tasks.

Great under pressure performer might fail in "as much time as you need" situation (and vice versa).
