I switched after running basic dev tools became genuinely unusable (randomly freezing for minutes, start menu just didn't work, crashes all the time) despite being on good, new hardware.
I never wanted to switch before because I just wanted an OS that worked, didn't require babysitting, and was compatible with apps. But clearly, Windows has dropped the ball on this.
I'm kinda shocked by how people thought DuoLingo was ever going to be any different. They are a high-growth startup, through and through.
The founder gets on podcasts and extolls the virtues of relentless A/B tests. They very openly admit that their primary value add is gamification (otherwise people churn from language learning apps).
I suppose the lesson here is that the words you say to Silicon Valley types you want to impress are sometimes overheard by your core audience, who may not like your opinions.
VC-land is a strange place with strange laws. If you stay in it for too long, you forget that most of the world doesn't follow the power law, and that most of the VC-reasoning just does not help.
