The first is taxation. Academia uses this. So we'll be fine there.

The second is donations and altruism. This includes Wikipedia, people who just want to share their ideas (like I'm doing now), Stack Exchange, etc. So we'll be fine there too, though this only works for low-budget stuff. Note that credit isn't necessary here; Wikipedia editors are rarely acknowledged, for example. But I do think credit is good, when possible (i.e. not for every single training source the LLM uses; ChatGPT Search is a good and practical way to give credit).

The third is to privatize the goods, for example, by creating copyright. LLMs won't get rid of this. They're not allowed to fully replicate a piece of text, since that is copyright infringement. So if you're getting people to pay for an exact or almost exact piece of text (e.g. a full book, a full newspaper article), you won't be affected there.

But if your business model would be affected by people summarizing your stuff, then yeah you won't be protected there. For example, if people would rather read a summary of your article or book rather than pay you for the full version. But this isn't new to LLMs. How many people jump straight to the comments to read the summaries instead of reading the article? How many people absolutely refuse to pay for paywalls? How many people block ads (I'm treating ads as a form of payment here)? It's possible to expand copyright to also cover things like summarization (i.e. copyrighting facts), but this is rather dangerous.
