the value of art hasn't gone down - the standards have gone up.

i watched a somewhat decent lesbian movie once

https://www.imdb.com/title/tt8613070/

where the entire movie one lesbian is trying to paint the other so that the portrait can be used to sell her off as wife to a rich man from overseas who can't see her in person.

today she could just text him a selfie ...

so art is definitely changed forever by technology ...

and the value of "pretty image" is definitely zero now ...

but that doesn't make art boring. unless by "art" you mean pictures of "bitcoins" and nostriches.

then it is.
