You can't walk into a room with the attitude of "I know best, move aside", even if you do. This aggressiveness towards 'the ignorant' is a dangerous and growing problem - partly fueled by the internet; 'a little bit of knowledge is a dangerous thing' as they say. You see it with the new wave of Atheists too, using every opportunity in conversation to create tension with their views. These self-righteous and crusading ideas about declining quality need to stop, people need to take the middle ground a bit more. I say this after recently selling my last DSLR lens, which hasn't been used for a year.
I was out of line to call him a jerk, so apologies, but I still think it's twisted to boast about ostracizing people.
I understand the movie situation. I've actually just watched 'Side by Side', a film which deals with the issue. Beside the fact that it's not a very good film, there isn't a conclusion drawn, even from great filmmakers at the top of their game. Even Wally Pfister, incidently, has come round to the digital idea. But I guess he has little choice, in the end.
