> I wish there was a good way to transfer these highlights from my Kindle into Anki flashcards automatically

Wouldn't the result be actually opposite from anticipated? It's exactly writing about the stuff by yourself a way for remembering it. It won't stick if you just automate the process. Or rather it will, for long enough to deceive you into thinking you know it, but you'd probably forget it after a while anyway. Writing anything by yourself, or ideally handwriting, makes it stick. At least it works for me. I spoke with some friends of mine and this system seems to work for them, either.

That's a good point. I'm not sure because I haven't been doing it regularly enough because of the friction of adding cards into the system.

I do want to note that once the cards are added to Anki, it will force you to review the card at the right times automatically to keep retention high. This is assuming you have a system that forces you to review Anki content daily. I am not sure how big of a difference it will make to keep retention high if you're not adding cards manually.
