... as always something good will probably come out of it.
I think you make an important point, here... and I think some good things have already come out of it. Davie504 has exposed a large section of the general public to bass, and more people are picking up the bass because of it. This opens the door to a major expansion of how the instrument is used. Davie504 has also exposed a large number of very talented players to the public eye, who will also influence new players and expose new players of their own. What about Charles Berthoud? An absolute chopsmonster on bass (who also has a strong musical foundation) that I didn't learn about until I watched a couple Davie504 videos... and I've played bass for almost 30 years.
Taken together through their collabs, these players are showing everyone that there is much joy to be found by picking up any musical instrument and getting together with someone, anyone and sharing the experience, regardless of how it comes out. To me, it seems experiencing and sharing joy is the whole point of music (and all art, for that matter).
It's like giving a box of crayons (the 64-pack, of course
) to a bunch of kiddos and turning them loose. They have a ton of fun expressing themselves and sharing those expressions with others and influencing each other. It's not sophisticated and lacks artistic foundation in the conventional sense. Those that are motivated to make a go of it on a more permanent basis will explore it more deeply and gain that foundation as they grow.
