I think there is something to be said for gaining 100 hours of solo time before joining the airlines and potentially flying solo with 150 passengers depending on your survival instincts.
Those who only fly modern airliners with auto-everything, with the occasional hand flying under a colleague's supervision, will have forgotten the latent terror in the backs of the minds of those for whom safe flying in 3 dimensions required constant attention and physical action.
Those for whom their flight training comprised primarily the sim and 10 hours solo, might never have known that feeling. And I think it does matter.
