All art is quite useless.

Our world is so glutted with useless information images useless images sounds all this sort of thing. It's a cacophony it's like a madness I think that's been happening in the past twenty-five years. And I think anything that can help a person sit in a room alone and not worry about it is good.

The value of old age depends upon the person who reaches it. To some men of early performance it is useless. To others who are late to develop it just enables them to finish the job.
