Next-gen optical disk can store over 14,000 4k movies

This is a most excellent place for technology news and articles.
And I believe 4k blurays are on average around 100 gb? So that will be about 1800-2000 movies. Still a lot, but not the 14.000 they say.
The rips I pirate aren't re-encoded and are usually in the range of 50-75GB, depending on the length of the film.
Hmm, interesting. I guess on actual Blurays they would have space for extras, menus, sometimes different dubs etc, so that makes sense!
