Clickbaity titles on videos or news sites is the new standard. I watched it. The point he's making is basically that music was harder to make/produce some 50 years ago, so there was more incentive to "make it worth the effort", compared to today. And the 2nd point he makes is that music consumption is now so easy as well (listen to whatever you want instantly) compared to when you could only listen to something when you bought the physical album, that there's also less incentive for the listener to really get involved into some albums.

Personally I think these are valid points on the surface but they are not "the answer" to this kind of multi-faceted question. They're at best a factor but we don't know how big these factors are. Also I think one big reason he thinks that way is because he grew up in that environment and so he has a bias for "owning physical copies of albums".

I also think music hasn't gotten worse, the market is just simply over-saturated because there's just way too much music, you'll never be able to listen to it all. And there are absolutely hidden gems or really good bands/artists forming even today, it's just much harder to find them. Generally a problem of today's age: it's likely that what you're looking for already exists, you just have to find it within a whole ocean of content.

If you're looking for innovative or non-standard stuff, you can always look at smaller artists or the indie scene, same is true for movies, games, music. The big producers always have a tendency to stick to what works and what's proven to be popular so everything becomes similar. But smaller artists do not have to care about such things, they are ready to risk much more and in doing so, you might just create a real gem or something that was never or almost never tried before.
