I hope we get some fucking legislation soon to control that shit. Artists and people in general shouldn't have to deal with everything they create getting ingested into a computerized regurgitation ripoff system. And even worse the "AI" systems could be ingesting tons of misinformation and repeat it to gullible people as the truth.
Of course, anywhere the potential restrictive legislation doesn't have jurisdiction, the bad things can still go on and probably will.
I expect Google to leverage their money hoard and 1.8 trillion dollar valuation to lift up the ladder behind them and neuter potential competing start ups with copyright law.
Reddits TOS make all your data in any future formats theirs to sell, so in this case the content has been laundered enough to be used, even if you can post copyrighted content on reddit (the legal expectation is reddit would remove it and Google's hands are clean).
