In general, cutesy UIs are fun only the very first time you use them. But they’re a liability in the long term because once the novelty of the cuteness wears off, you risk really annoying your users, and especially in high-stress scenarios.
Somewhat off topic but this is what turns me off about Jarvis / Friday during rewatches of any MCU properties. So unrealistic to have quippy AI be useful in the midst of combat.
Also: I just realised that the Avengers would never happen if Stark just realised that launching Jarvis as a product would take the world by storm :D
