In the age of the social feed things are currently tipped more towards the selector/curator/consumer, where before, when all you could do was listen to songs on the radio, it wasn't really possible to participate.

But culture will always be fundamentally about 1:many - we have to collectively agree on liking something- algo-based feeds are making the number of people that agree smaller and more siloed, but the dynamic is still the same.

In that sense I don't think truly 100% algorithmically created and promoted content could ever truly become cultural- at the very least humans will always ascribe some meaning or motive to it, e.g., when instagram launched AI generated accounts some people pointed their finger at Mark Zuckerberg, tracing something back to a human they could ultimately hold responsible.
