I think it’s likely that, unless regulated, commercial LLMs will have a chilling effect on most human-created information sources. With eliminating the opportunity for authors to engage with information seekers (a chance to get constructive feedback, upsell something, show ads, see interest stats) will come reduced willingness of authors to publish.
If you publish on StackOverflow only for LLM to gobble it up and no human even sees the upvote button anymore… why would you? You are basically an unpaid ghost content producer for Microsoft/ClosedAI at this point.
