Linus Tech Tips - How to rip blurays/4K discs to your own server and reencode then if you want to, the history of copy protection and the benefits of physical media. Quite interesting.
As far as I know Blu-ray is still being produced Sony just stopped making base media.

That sounds like consumer BRD disks not what businesses buy to produce copies of a new movie they are releasing.
That's just recordable Blu-rays, for the 5 people that have a Blu-ray writer. Nobody uses them, USB drives are far more convenient and can be bigger anyway.
Normal Blu-rays are not going anywhere.
Pressed discs are alive and well. Sony has been outsourcing Blu-ray manufacturing for years anyway, so the recent announcement changed nothing. BD-Rs are probably on life support, though.
