This is entirely different. Copilot and Chatgpt doesn’t exactly reproduce the code. It’s paraphrasing it. By your logic you’re not allowed to implement anything as the majority of algrithms originate from scientific research and papers that also have copy-rights on them.
Blu-rays do not actually take up this much space: On a 1TB drive you can store about 10-12 4K movies. You need a backup and you need a second drive for your Raid setup. This takes up quiet a lot of space too.
Besides that: storing the movies on a Raid system is a lot more expensive. If I’d rip all of my blu-rays to a digital copy, I’d need like 12 TB of storage. In a raid setup with backup, that’s quiet expensive!
