> what would we lose?

Who is "we"? Going back to the origin of Free Software to proprietary printer drivers causing hardware to be unfixable by its users and otherwise become ewaste. The loss is users are nearly beholden to the manufacturer to customize or maintain their own devices. Android phones, most ereaders, can have long lives when obsolete, but this is only because Linux is Free Software; with proprietary kernels they are entirely ewaste instead of a small fraction having continuing life. OTOH most do become ewaste. OAH this Free Software allows competitors to start from almost the same place and prevent total monopolies, hence why Apple makes most of the profit and I can buy a $150 phone instead of what appears to be $799 minimum from Apple.

But, I think 20 year-old software is probably mostly safe from the above effects and I'm not sure GP was arguing otherwise, just against total absence of copyright.

> Most projects are MIT or some other permissive liscense.

Exactly, most projects have a license of some kind, they aren't "free-for-all-do-whatever."

MIT requires attribution. Forcing enforcement of this cannot be done without copyright law. You can argue that attribution is stupid and nobody deserves credit for their work (which might be increasingly true in a post-LLM world), but you can't speak on behalf of all projects that chose those license and say "it's what they want!"

Aside what was already said: a lot of people do genuinely think GPL is a stupid idea that needs to go and Linux could have been licensed under MIT or even CC0; however, I think one should be cognizant of the fact that virtually no mass produced product other than Macs and PS4/PS5 use BSD and the rest uses Linux, often begrudgingly, but benefiting tremendously from both free-beer and forced-libre nature of it.

This. Some people here are now acting as if AI is a bad thing. People need to realize that human knowledge is so vast now that such tools (which effectively perform data compression and interpolation) are absolutely necessary. I don't feel bad for copyright holders at all because copyright shouldn't probably exist at all.

Is it still a worthy goal if it the knowledge includes the rantings of every lunatic on X or Reddit? If it hallucinates facts and even citations in its non-deterministic reconstruction of the knowledge it ingested?

Authors and artists have no basis for payment in the absence of copyright laws. Like, anything they make would be literally free to steal. Literally... 1700s? Late 1600s?

What would be controversial is the current form of copyright that had been extended and expanded multiple times even during lifetime of many of us alive, often said semi-jokingly said to have been forced by Disney to keep Mickey Mouse covered under it until it had finally expired 70 years after the first publication and long after the death of its creator.

I don’t necessarily disagree, but by that same logic we shouldn’t have any civil laws because regular people can’t afford to hire lawyers to sue people.

But still, if someone posts a copy of your book or painting online, you can pretty cheaply file a DMCA request that it be taken down, and most large players will comply. If you throw out copyright law altogether, you get rid of that too.

All copyright does is give you standing to sue if somebody reproduces your work, in whole or in part. To sue "successfully," you need more financial resources than the copier.

The small artist copyright is a red herring. I think the number of small artists who make money from their work is frightfully small. For example, my partner makes some rather nice jewelry that is different from anything out there. We're doing the craft fair circuit to see if she can sell any and if it's worth continuing to make them.

She sells a relatively small number of pieces at each fair. Occasionally it's even enough to cover expenses.

Would copyright help her? No, because we wouldn't have the money to sue. Small copyright violations might be worth a cease and desist. Large copyright violations would have more money than us for the lawsuit. We would need that Goldilocks-sized violation. They are small enough to be responsive to the threat of a lawsuit but big enough that they have enough money that would be worthwhile suing them, i.e. enough to pay our lawyer.
