I haven't used it in a ton of games yet, but in the games I have, it's worked out pretty well so far. As long as it doesn't add too much input lag, why wouldn't I want to use it, since it generally seems to look OK? Besides, as far as I know, it's really just a particularly good interpolation method. We could probably have had frame generation way before AI, only it would have looked worse.
The part I don't love about frame generation is that it enables developers to cheap out on optimization. I don't know much of that actually happens, but on some time scale, it undeniably does or will lessen the pressure to optimize games further. But since frame generation is here, for better or worse, I might as well utilize it. I guess if I hit the refresh rate of my monitor, I could skip using frame generation, but that doesn't really happen a lot, at least not without significant sacrifices in other areas.
