Oh, no. We've spent years thinking about it.

Probably the thing you're losing is efficiency. By that I mean amount of content learned per unit time. You're probably losing efficiency. I mean, the truth of the matter is I grew up, first of all, I grew up in the third world a while ago. some of the stuff that I grew up being taught, my teachers were like hitting me and I'm not kidding. Like they would hit me.

And the reality is that I probably learned really fast because I like, you know, like when you were learning penmanship, like if you did it the wrong thing, they kind of would hit you with a ruler. You have a real incentive to get that done very fast. You just learn really fast because you're like, whoa. You know, I think so. I think it's true.

You can learn faster if you're in an environment where you're forced to, you know, just do so. And nobody cares about whether you're feeling good about it or not. You can probably learn faster. But, you know, in our case, I'm okay with slightly slower learning as long as you're still engaged.

Yeah, and there's probably a little bit of that. Very hard to measure, of course. But the reality is, I mean, ultimately, it works. Duolingo works. I mean, just an example. For me, I've been, for the last few years, only using Duolingo to learn French. At this point, I can watch Netflix shows in French. And with no subtitles on it, I just watch them. And it works. So you're right.

There's probably a trade-off. It's probably pretty hard to measure. But what we're looking for here is, that people are actually using their time well.

Yeah, it's a good point. I mean, well, first of all, math and music are about to be available on Android, or by the time this airs, they will be available on Android. So we are about a year behind on Android. The reality is this has been true on Duolingo almost since the beginning. Android has been... six months to a year behind iOS.
