I'm talking about the problems that a long running company fails to solve for years or decades. The ones that it has become the norm to think of as insoluble. Especially areas where you have been asked to solve a symptom, and instead you solve the cause.

Yes regular stuff gets solved quickly and reliably.

When you solve those kinds of problems, you have a new business, or maybe a new industry. You probably don't have a quick route to CEO of the fossilized company. That involves daggers in the back of your colleagues.
