>> Copyright is serving exactly nobody today.
Are you sure about that?
So just to be clear;
You're advocating for the end of software licensing? Ie the removal of GPL or Open Source licenses? A landscape where any source code (or binary) can be snapped up by say Amazon or Microsoft and run via a paid subscription?
You're advocating for a business model which removes your access to local code and only allows access via a terminal or browser?
Because removal of copyright doesn't mean corporations go away. Rather it incentivizes business models that protect their products in other ways.
In the 80's and 90's, pre-internet, binary programs were distributed on media. An arms race of copiers and copy protection ensued. The copiers won, and since copyright enforcement has always been weak, business changed to favoring remote access (with subscription) over running locally via purchase.
At the same time Open Source and Free Software have thrived. Copyright protects that software being used outside the terms of the license. Indeed there's even outrage when it's used within the terms of the license (by AWS etc.)
Of course OSS still thrives under a copyrightless environment. (Free Software less so). But equally it means AI can simply be trained on it (probably no great loss since it's likely most of OSS will be AI generated anyway.)
Business however will adapt. And the easiest way to prevent coping now is simply remote execution. With a suitable Terms Of Use declaration.
Outside of software it would destroy music, movies, books etc. Basically it becomes a race to the bottom in terms of production costs (think user-generated You-Tube as the high-water mark.) But I assume you meant in the context of software.
Yes, I agree, that in much less than 1000 years copyright is dead. Because by then so much is in the public domain it doesn't matter anyway. Also because by then the last human programmer is long dead. AI will write anything you want, only you won't even ask because computer interfaces and abilities will be long past where we are now. You would have no need to create software any more than you need to build a plane or car today.
And those industries have taken less than 150 years to invent, explode, consolidate and commoditize. Indeed most of the complexity disappears when we go EV.
In 1000 years copyright is gone. But today it serves a lot of people.
