Do you find some mathematical activities useless?

I would draw a thick line between beauty and usefulness here. I know that mathematics is useful, to a degree at least. But I see no beauty in it. For me some things are beautiful that could not have been made without advanced mathematics - my most striking example being the Concorde. But mathematics in itself is about as beautiful as any other tool, be it a screwdriver or a 6 degrees of freedom milling machine (which requires some medium complex mathematics by itself to work).
