That seems like a silly argument. The amount of time a person has to invest to be trained sufficiently to fly an airplane is huge. The amount of time required to then have to pick up completely different user interfaces probably doesn't seem very large by comparison.

But could you imagine having to spend large amounts of time training for every mundane interaction with technology around you? The way aeroplanes work today there probably isn't a way to make flying them intuitive to a novice, but that's not an argument to make everything else painful to pick up when it doesn't need to be.
