Re: So much for copyright!
An author can't prevent me from telling people about their book or article I read"
No, because that's not 'reproducing' or 'using' it. Trawling a verbatim text or an image and making use of it is 'reproduction or 'use' and is subject to copyright in most jurisdictions. 'Fair use' may or may not qualify this depending on local legislation. In the UK it's perfectly legal to restrict any reproduction in whole or part without permission (as seen in the rights notices of most published books these days). Where this applies, it applies whatever the use - whether it's for 'training' systems or not is irrelevant.
