I've had the setting for AI features turned off in gmail for many years now and am quite happy about it. Using the "dumb" version, there isn't a single feature I've wished existed that might be under those settings. Maybe there are some that would be mildly useful if I'd tried them, but eventually I would get rug pulled by google and have to redo my workflow without them anyway; better not the waste the time to begin with.

Along with the author I also have zero doubt google maliciously disables non-GenAI features under that toggle to coerce people into enabling the slop features as well. Google being google, I fully expect them to remove that option entirely in the future, forcing all users to wade through useless slop. That'll be the impetus for me to finally get off of gmail once and for all.
