Acquiring good taste comes through using various things, discarding the ones you don’t like and keeping the ones you do. if you never try various things, you will not acquire good taste.
This is the core point I was hoping for. I don't think it's super well supported or well argued here. But it shows up.
We don't know who we are unless we try new things, unless we put ourselves through processes of discovery. Taste comes from trying, and the tinkerers are down to FAFO.
