> But the value prop of the company isn't the software, it's the ability to solve business problems.

Clearly it's critical to the job, but to take your point to its limits: imagine the business has a problem to solve and you say "I have learned how to solve it but I won't solve it nor help anyone with it." Your employer would not celebrate this, because they don't pay you for the private inner workings of your own mind, they pay you for the effects your mind has on their product. Learning is a means to an end here, not the end itself.
