Of course the blog post fails to mention how a bot using the same API masqueraded as a democratic presidential candidate for months but at least people are beginning to develop some awareness on the matter of AI chat bots.

The cool thing about GPT-3 and GPT-2 is there doesn't seem to be any plateauing of ability. You can just keep increasing the number of parameters and they just keep getting better. The only actual ceiling as far as we can tell is economic, it would just cost too much to train a potential GPT-4 with the same ratio of new parameters (and I don't know if there's actually enough written language out there including all of history to train something with a few trillion parameters).
