I don't think the real problem is proliferation of AI itself. The real problem is control of AI. We need to commoditize and replicate FOSS AI models as soon as possible, and make progress with optimization so they can run without megacorporation levels of resources, so that they aren't able to retain exclusive control of AI, which lets them grow even larger.
Seems to me that every time someone spends millions training an AI, a cheaper version that does the same thing comes along in a few years that everyone can use.
It’s going to be very difficult for anyone to retain ‘control’ of AI when they’re fighting a running battle against Moore’s Law & The Bitter Lesson.
So you think the problem of high-tech spambots is that there aren't enough people using them? Is your goal to make forums and such unusable as fast as possible?
This is happening regardless of our desires. The best we can do is to be prepared and have the tools not available to only the most powerful few, but to ordinary people as well.
