It's about to become uncontrollably bad. With really powerful artificially generated writing available, spammers will develop it to be indistinguishable from real human writers when analyzed by google's own machines. We're going to have billions of websites that are 100% generated, with content that most humans can't distinguish as entirely generated, and a LOT of it is going to be wrong. It will completely drown out human written content to the point that websites using humans will give up, and there will only be spam left.
