The number of people does not mean much.

Fine with me. I was under impression that you are implying that people become artists quite often, due to this apparently ironical statement

Because, obviously, they will be very important in our futures -- especially if we become artists, musicians, writers, actors, and business people.

Sorry for misinterpretation.

My point is that people should be educated in more areas, so that the scientist understands part of what the artist's work, and the artist understands part of the scientist's work.

Note that the artists don't usually understand much of science either.
