While I agree with everything you said, there are companies like Moment that are doing some very interesting things with add-on lenses for smartphones. I've been having a LOT of fun with their macro and wide-rectilinear lenses on my iPhone X. Their 60mm tele is nice too when you add it to the iPhone's tele lens, giving you 4x optical zoom. It won't replace my 5Dmark4 any time soon, but you can get some really nice photos.
