I’m under the impression that ps4 discs are pressed. This article is about writable media.

Writable media needs a dye or layer that can be ‘burnt’

Commercial disks don’t do this and instead are physically pressed.

The dye material is the one that degrades over time. The pressed material doesn’t.

Someone correct me if I’m wrong?

Commercially pressed discs should last a very long time in comparison

Basically correct, with a tiny caveat: there can be manufacturing defects where the reflective aluminum layer of pressed discs is not fully sealed and oxidizes over time.
