Because they are playing the flute and they are playing football. They enjoy it now and that's what counts, they don't even think about the future.
And yet they come into my math class and raise their hand half-way through my demonstration of the mean value theorem to ask me when they will ever use this.
Because the "mean value theorem" sounds like boring shit and their only hope is that it may be useful in the future.
If you teach them programming to solve their physics homework and make it a game using math, they won't ask.
Never.
