This sounds wildly optimistic. I buy the metrics compilation, but I'll be damned if there's any PM at Microsoft (or Apple or Google for that matter) who's interested in '[optimizing] the calculator layout to improve the UX.'

I need that Drake meme here, where he's negative about the idea "Optimize the calculator layout to improve the UX" and very enthusiastic about the idea "Find ways to get incremental revenue from users of Calculator with ads or selling of data"
