Beethoven's influence on the Western classical music tradition isn't disputed by any expert in that field - it truly was outsized and unmatched by any other individual composer. I'd accept the Beatles probably deserve the same recognition re popular music. It's fair to wonder how transformative they would have been if they'd existed in an era of Tiktok, Tinder and Snapchat.
Beethoven (or the Beatles)'s influence was not what I disputed. Rather, I dispute the assumption that the fact that they are the most influential automatically means they are also the best or most innovative.
I don't see it as a debate about "best" or even really "most innovative", just about individuals (or pairs in the case of Lennon/McCartney) that achieved a level of greatness (in terms of what contributions they've made to human knowledge/creativity) that logically you might expect to see a lot more of today given the vastly greater number of humans in existence now.
I wonder if "levels of greatness" is a relative quantity. If fourteen living composers are objectively as good as Beethoven/Lennon/McCartney (as one may expect with a much larger population), none of them will be recognized as great as Bach.
