IMO the core idea of copyright isn't nonsense, but I do think the current implementation (70+ years after death) is egregiously overpowered. I've always thought the current laws were too deeply entrenched to ever change, but I'm tentatively optimistic AI will shock the system hard enough to trigger actual reform.

I think AI is very much eroding the legitimacy of copyright - at least to software, which is long been questioned since it's more like math than creative expression.

I think the industry will realize that it made a huge mistake by leaning on copyright for protection rather than on patents.

Probably a wiser approach is to consider different times require different measures (in general!).

I did not study in detail if copyright "has always been nonsense", but I do agree that nowadays some of the copyright regulations are nonsense (for example the very long duration of life + 70 years)
