All art requires growth and change. Artists can't go on doing the same things forever. Will they take a turn into some dead end...sure. Maybe even for centuries. But remaining static is certain death.
dude take one single art history class... (well, maybe 2 since the first one is going to give you the venus of willendorf and ionic/doric columns...) this is nonsense.
If you need a class to tell you what’s enjoyable to look at and what isn’t, then it’s not a class it’s brainwashing to suppress your natural instincts.
