I think there is an important third category beyond "avatar of techno-optimism" vs "advocate of caution". Artists typically oppose GenAI because the models are trained on huge swaths of copyrighted works. They certainly aren't supporters of the tech, and they aren't concerned about the risks of a new, not-entirely-understood technology either. They think it's outright stealing, copyright infringement, etc.
At the risk of lossy compression - every take in the AI debate is downstream of this dichotomy of perspective.
