As agencies produce more and more content using AI, since it's so easy and cost effective, the content itself will start being fed back in and consumed BY AI during their learning processes.
Wikipedia editors will certainly start using it.
Professors, in response to students using AI to answer, will start using AI to fashion their questions.
We'll all bear witness to the machines learning from each other.
And getting smarter than us.
Eventually we'll be just smart enough to keep the machines running, and how to prompt them, but not really smart enough to understand what they're talking about.
