So I am totally aware that when I defend the autonomy of art I'm going counter to my own development. It's more an instinctive reaction, meant to protect the private aspect of the work, the part I am most interested in and which nowadays is at risk in our culture.
If the whole process of learning from failure means discarding stuff that's not working, but in fact, our natural reaction is to keep going, to throw more money behind it, to throw more emotional energy behind it... that's a real problem.
