There are plenty of hard problems that need solving.

One co-worker, for example, has headed up the team that convert the proprietary RAW format from various camera vendors to a standard RGB format that can then be edited/adjusted in Photos, etc. The cameras (vendors) never rest and as such he's kept quite busy.

Another coworker was the guy you turned to who could walk a stack, read registers, and then tell you that you were trying to dispose of an object on a different thread than you created it on (and the framework that handled the object had stashed important data in the creation thread that it needed for disposal—bad framework).

I turned to another coworker when a stack of transforms had my brain in a knot (early bring up of Preview to allow scaling (zoom), translation (scrolling) and rotation while trying to select text (hit-test in the transformed PDF). "The matrix you want to invert should have been created in the reverse order of the transforms that you had applied when displaying the PDF." Oh.)

And then there were the GIT experts that could somehow fix the completely fucked up state I had got the project in…

And the Smart Guy™ who, glancing at the debugger, might announce that I had exceeded the number of threads allowed per process. (I had no idea there was a limit.)

Come to think of it, maybe I'm just an idiot. :-)
