How long til Blu-rays get phased out (lemmy.today)

Basically just the title. With DVDs getting tossed to the wind it made me wonder when will blu-rays go? I'm gonna miss bloopers and extra scenes

Edit: A bit confused but the general consensus is that in some areas BRs have already began to be phased out while in others they're just trucking along perfectly fine. It'll be that way until they stop being profitable to the studios who make them. Is that correct? I don't think the 8k argument is valid imo since that's really niche currently.

I think it was done with wax cylinders first, somewhat earlier! So at least for vinyl, there was strong technological precedent.

In the early days, it was quite a simple device! Sort of a cone to focus sound waves, with a membrane at the end attached to an engraver that carves wax. I bet it was quite hard to make those mechanical systems reliable, but I can sort of see how someone goes from "sound is a pressure wave in air" to that device!
