This should be obvious, but even children will invent basic language. You only need to look as far as the deaf community for that, that always came up with pidgin languages even as they were forced to try and learn spoken language.
There’s an interesting free short documentary here: https://www.bslzone.co.uk/watch/history-deaf-education-1
Are you sure about that?
I’ve read both articles and they both seem to say they are stopping production of Blu-rays, plus three other formats.
It mentions that consumer recordable Blu-rays were already dropped last year.
Still, this might just mean that Sony will no longer make games distributed via disc. Sony does not have a Monopoly on making Blu-ray discs, and I do not believe they can unilaterally decide that no more will be made by others

Regardless, it is a sign of the times, with Blu-ray reader production being recently stopped by LG. It’s likely all downhill from here, as much as I am sad to say.
I will resist this as much as possible, as I like owning my media. If you give me no means to own my movies, then I will find other ways to acquire them.
