Doing some curious reading on 100GB optical discs, 4K/UHD Blu-Ray discs.
Unsurprisingly, many of them were protected by Intel's #SGX, presumably to prevent piracy.
However, you would need an Intel CPU, and some newer Intel CPUs won't even work with these Blu-Rays anymore. And, as usual, people found out how to copy it anyway with some modded drive firmware and the right software.
If you have #DRM -"protected" media, understand that at some point it may be taken from you.
