I've already received work almost certainly written by It. My AI-dar was tingling as soon as I read it so I decided to run it through a few detectors, all of which suggested a 99% chance of AI involvement.

I've played around with it a fair bit and it's very impressive. Undoubtedly, AI will replace a lot of jobs in the near future so the world needs to start planning for it.
