I fully understand this. And I shared the same skepticism. The thing is the more you anki, the more you find yourself being able to make connections between concepts and thus come up with creative solutions to problems because you’ve developed such a substantial knowledge base—and that’s the big benefit of Anki. It’s not so much that you can memorize things in the blink of an eye (although that can come in handy), but more so it’s an efficient way (in terms of cognitive load) to build up a knowledge base to draw on when solving problems. I’d be curious to hear others’ experiences, but that’s certainly been the case for me.
At the end of the day, like anything, you’d just have to try Anki to know for sure if it can bring you value or not. And maybe it does or doesn’t. Either way, I can’t think of much downside to giving it a whirl.
