Harm Reduction Guides for Mainstream OSes?

Hi y’all. As time progresses, and AI becomes more and more integrated into the mainstream closed-source OSes like Windows, macOS, iOS, iPadOS, and Android, I feel like it’s going to be increasingly important to teach people how to harden these OSes to reduce harm. We already know that the integrated AI can be a threat to many of the E2EE products we recommend on this site (the Signal president gives interviews about it, and it’s been discussed on this forum). Do any of y’all have favorite trusted resources for hardening guides that ideally involve hardening against AI features and are updated regularly? I wonder if this is a list we could keep compiled on the wiki, or if anyone would want to collaborate to make these guides if good ones don’t already exist?
