Looks like it's learned that adding "according to Quora" makes it look more authoritative. Maybe with a few more weeks of training it'll figure out how to make fake citations of sources that are actually trustworthy.
Google signing a contract with 4chan for data training is actually so stupid I don't think it'll ever happen.
4chan is almost certainly blacklisted from basically everything AI given the sites content and history of intentionally destroying chatbots/earlier 'AI's.
