Is running an art/vocation comparable to photography and/or painting? We no longer have mailmen who run the length of the country afaik.

But running did heavily contribute to sedentary lifestyles in western countries, along with a bunch of other things.

I agree, I think it will move from mathematicians "doing" math, to managing computerised system that do it instead. I'm sure we already have such systems.

I think far more important to humanity is improving mathemetical-literacy. From my perspective, math is made for mathematicians - it could be more accesible. As "pure" amth matures, there is still plenty opportunity in "applied" math (however you might define it).
