Couldn't agree more
Why write books or any creative text based content when the second it's available it will be hoovered into the next AI training cycle and can be reproduced in part or in whole by users who almost definitely do not know who you are in the first place.
Personally I think the only way forward is for these AI companies to curate their dataset to only material that is legal for use. E.g. only GitHub repos with licenses stating such. Just because there is not a license doesn't mean it's free to hoover.
They could buy a bunch of content created (or specifically licensed) for purpose, the artists get paid, and the artists that don't want their work to go into the pipeline get what they want too.
But too many people consider the development of AI to be such a moral imperative that no objections can possibly be relevant.
