If they deem the content valuable enough, I get the feeling that they'd instead just correct for it (e.g. auto-correct mispellings; replace and/or omit curse words).

It may get to the point wherein the only way to secure content is to hide it behind a paywall or otherwise make it non-public, then forbid via the TOS. There'd probably need to be court challenges even then.

I also wonder if the LinkedIn case involving scraping (wherein the ruling was essentially that public data was fair game), will be re-tested in the age of AI.
