Not talked about enough: products live or die depending on the *feeling* of power they give to the user. Too complex and users don’t feel powerful, they feel stupid and overwhelmed. Too simple and users don’t feel powerful, they feel frustrated and boxed in.

Nuance is that "user" is broad and what is "just right" for one user may be too complex / simple for some other user. Ex: @figma feels "too complex" for non-designers, while canva feels "too simple" for professional designers. Holy grail of user experience is that it feels "just right" for ALL users. AI is getting us closer and closer there.
