Count me as severely skeptical. I don't exactly feel like digging through the entire prospectus since it's too late to matter, but a quick search seems to indicate their user and revenue growth was fairly flat for years until last year, which just happened to be the year everyone in the world was forced to stay home and find somewhat productive things to do. Investing in this doesn't feel any saner than investing in a startup for people making sourdough at home. I can at least squint at something like Zoom and say sure, single-year growth like this is never going to happen again, but at least remote multimedia collaboration is probably here to stay, even though Zoom specifically isn't necessarily going to monopolize it just because they were first. But that has a clear business use case that isn't going anywhere. Duolingo is relying entirely on the whims of the general public.
