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 sympathize with the reason why students cheat, but I can't see that those reasons are the same as what you say. You don't need to attend classes to learn the content nor display mastery - I appreciate a good syllabus for that reason where you know what is expected and can learn on your own time. I liked the approach the author of the article took for that reason. But none of this requires cheating.
I can see why this would lead students to cheat, but this looks to me like a strawman in addition to victim blaming (on part of the prof).
Jacob Collier has a good example of this[1] (I'm a huge fan).
Separately, I've previously heard this referred to as "equal temperament" tuning which makes me wonder what led to this difference in wording.
If one can't empathize, I'd hope one would at least be able to sympathize with another's objectively different situation.
Now to see if I have the discipline...
I actually really enjoy the ability to effortlessly discover new music I never would have found otherwise that Spotify gives. The recommendation algorithm can be weird at times, but I hear liberal use of likes and dislikes helps though YMMV.
As an aside, everyone else I've seen using Spotify tends to strictly build playlists and not really follow any artists. Not really sure what to make of that.
