Query: Those who can't , whine about those who can.

Mr. Hockney should be embarrassed by his claims. If he thinks the old masters work is so good because they used tools, he is sadly misguided. If that were the case, Mr. Hockney's art would surpass that of the old masters, given the technology available today. Reading this book is akin to listening to a whiny, jealous child.
