I think part of the reasoning is in the trades there's the presumption that to be a master you must also be old (with exceptions, Da Vinci was active when he was still younger, 20).
In the programming industry, there's likely a bias more toward younger people, and hiring offices ask for the world. They'd like a whole staff of masters and rockstars. Though that doesn't preclude "older" people from being known as masters either. Take John Carmack or Jonathan Blow, for example.
That is a interesting thought, that seems to imply that those young programmers will not improve. If you are a master at 25, what do you call yourself after you have gained twenty more years of experience? It may be that those 25 year old's a more like journeymen then masters, or that programming is more like sports where youthful vigor are more important than experience.
John Carmack programmed Wolfenstein at 21 and doom when he was 22. At that point he did what most "masters of that craft" couldn't do. What would you call him? And what would you call him now, 30 years later?

Something else than thirty years ago, because presumably he has developed since then.
I think that was why GP suggested "journeyman" for younger people, because otherwise there's nothing to differentiate young "masters" from masters honed by thirty years of additional experience -- except adding the whole phrase "with thirty years of experience", which is pretty clumsy.
