I love audio. Stereo audio was performed in the 1930s, but so late as, let's say 1977, since Star Wars purists are still fighting about it, the mono audio is often preferred. (nice of them to give me a late reference) Sure FM radio mostly featured new artists in stereo years ago by then. Listeners still requested those old mono Beetles, Elvis and Beach Boys. Those were remixed stereo later with not always the best results.
Ain't technology fun? Stereo is just the default now, 5.1 home editing is getting more common. Some of the ASMR artists are experimenting in VR, but I see little point as of yet as the audio doesn't track with the view yet. Six months from now I'll be quoted as an idiot for saying that. Five years from now you won't have to say you're an ass man, or a feet guy, your profile will select your view based on your previous sessions...how boring.
I'd love to see this tech whirlwind blow into cam sites so they go stereo. Then let's leave it there. I don't want 4k cam sites, or VR. There's a point where better quits adding to the good. Or maybe I'll be quoted on that in six months too.
Apologies, spleen needed some air.
