I think Rob fails to see the guy playing the guitar has the mindset to take it upon himself to go and find his own audience that will appreciate his work. The guitarist could be a session artist, locked away in a studio providing minor contribution to someone else's masterpiece; putting him on par with Rob and his lack of vocal appreciation he receives as a programmer.
Rob could find the same fulfilment and admiration if he was to go and create his own work to display his talents to an audience. For example releasing an app to one of the mobile markets could draw a decent parallel to the attention the guitarist receives. The first piece of feedback about your work feels as good as the thousandth. It may take a little more to get the cute girl home but having your own project that's openly admired by X amount of folk is a few steps up the ladder.
