FWIW, my anecdotal 'evidence' is that when visiting the NW Audio Shows over the past ten years (apart from the '20/21 Covid cancellations), I can't say I've noticed any drop in visitor numbers there.

Ofc the demographic stays pretty much the same, but so what? Some could say that as kids grow into their 20s and their prefrontal cortex develops, they move away from TikTok and similar moronic persuits. This doesn't mean the end for TikTok, as there is a steady supply of new morons to replace them.
