Agreed, and guitar-oriented music isn't the same as it used to be - or at least from the observations I've made as a sample size of one, that which resonates with newer generations.

Polyphia is one of the big bands that are fully instrumental and also maintain the spirit of virtuosity (more aligned with metal than rock, but the guitar-centric piece is there). There are other amazing guitarists and artists in a fairly interconnected community such as Jason Richardson, Plini, ichika, covet, etc.

I would likely agree overall interest has waned as it's not as mainstream as it used to be. But I'm more inclined to say guitar-centric music seems to be going through more of a transformation to fit the mainstream or certain niches than sunsetting as GP said.

I mean that kids are taking up the guitar less and less. The vast majority of guitar sales $ comes from the older generations who will eventually age out of buying guitars.

This is strange because the numbers I'm looking at show guitar sales have been rising steadily since 2012.

Where do you get your data?
