Here are some food for thought from Seth (see his blog entry for more),
“Classical music wasn’t always ‘classical’.”
“So classical music gets stuck because the new stuff isn’t like the regular kind, the classics. French food got stuck, because no restaurant could risk its 3 stars to try something new. A convention can’t change cities or formats. Schools can’t start their curriculum over… the culture gets stuck because the masses want it be stuck.
That’s because the late adopters and the laggards have plenty of money and influence–while the early adopters have a short attention span and rank low in persistence.”
