I just substitute the phrase "robot that doesn't know the foreground from the background" whenever I read AF.
It makes phrases like "The GH6 won't be successful until it has the DPAF from Canon or PDAF from Sony" sound ridiculous, but also more accurate: "The GH6 won't be successful until it has the Dual Pixel robot that doesn't know the foreground from the background from Canon or Phase Detect robot that doesn't know the foreground from the background from Sony"
I think most people here that talk about AF are either wedding shooters thinking that their films will be better if they can get shallow DOF on their circling-the-couple-gimbal-shot (they won't be) or tech nerds that don't shoot at all.
I came on this board thinking that Canon colour science was the best, 4K was required to get a good image, and that AF was a critical feature. Now I know that most of the manufacturers have great colour science, but that magic is created on-set and in post not in the cameras internal LUTs (even if it's an ARRI), I shoot manual focus, I shoot 1080p, and I think possibly the largest weakness in current cameras for image quality is dynamic range.
How did I progress on that journey? I shot stuff and looked at it and worked out how to make it look better. I learned about what actually makes a nice image vs just reading the marketing BS that manufacturers spew at us constantly. Guess why? Older cameras can potentially make nicer images than newer ones - no wonder that's not on the marketing talking points!
