"It is so characteristic, that just when the mechanics of reproduction are so vastly improved, there are fewer and fewer people who know how the music should be played"

This quote by Ludwig Wittgenstein suggests that despite advances in innovation and scientific advancements, less people have a deep understanding and gratitude for the arts, such as music. The focus on enhancing technical aspects might come at the cost of the imaginative and artistic aspects involved in developing and performing music. Wittgenstein seems to lament this loss of understanding and gratitude for the arts.
