Like any filters for spammy bullshit, they just need to be improved. That's the cycle for any new development of technology. We didn't know how to discern the difference between photoshopped images and real ones, then people smarter than most found it leaves artifacts in the images that can be detected.
The same will happen to AI where real and generated will be fenced off from each other. Is it bad literally right now as it's developing? Yes, of course. The anti-measures will come soon. AI is a tool that has the propensity for being misused like anything else and the reactionary take that it's "going to kill everything we love" is just frustratingly stupid.
