A lot of people in the comments are making a hard distinction between AI garbage/bullshit and the pure/genuine human-created thing, and the various ways in which we can keep this distinction alive.
If only that was true, the bullshit part. You should start living with the idea that the AI generated content is NOT bullshit, because we're either already there or very close to it. The AI content will be of value, look good, pass tests, and be indistinguishable from human-created content for a large amount of use cases in mass media.
So I wonder if we should ask, how do we filter out the bullshit? The more relevant question is: if its indistinguishable in its output compared to humans, what does that mean for our economy, purpose and humanity?
Because without action, the future is easy to predict. 3 companies run AI, feeding on all collective human cognitive labor without paying a cent for it. Then, one by one, it will wipe out every creative/cognitive sector, or at least decimate them. These shocks to the economy and culture will lead to a brand new type of pushback: anti-AI activism. That won't do much because AI doesn't care. Finally, some 10 years after the catastrophe there will be a congressional hearing where a 75 y/o asks: "so this AI thing, it's like a better calculator, right?".
It would be another fine case of humanity failing to grasp the exponential function.
