A standout quote of your response with emphasis (mine) on two key words and two key ideas:
“I don’t like observing exploration without a product. Exploration is a means to an end, a private step on the road to a great masterpiece…
If the artist will not attempt to express their findings in an appealing way, why should I care?”
Like & Should
The thing about art, and most things in life, is that it’s perfectly okay to dislike something that someone else likes, and to not care about something that others care about.
Dislike and apathy are acceptable reactions. No one compels you to be interested or moved. There is no art police that will enforce appreciation or concern.
Private Process & Appealing Result
Although exploration may be a means to an end, it doesn’t always have to be. It is not defined by being private or resulting in a masterpiece.
(Interestingly, it is defined as the action of traveling in or through an unfamiliar area in order to learn about it. Nothing more, nothing less.)
