I think that's just the problem... many never willingly go when it's time. And as things evolve, they just gradually fade further and further into the past. Consider that we're experiencing an extraordinary amount of change, and that there will be a wave of new changes once the N/S guys finally agree on Best Practices through mutual experience... And we'll be stuck with guys that are still talking about the autothrottles on the L-1011, or how surprising easy to land the 747-200 was.

I prefer to be taught by people that have to perform the same tasks on a routine basis.
