I see spreedsheets more as an UI. An extremely intuitive (and reactive!) way of spatially decomposing computation. Yes, this creates lots of problems (you can not easily validate it etc.) but it is also very enabling. For sure more people are now exposed to programming, but how many are actually comfortable doing even simple stuff directly using code is a question mark.
A jupyter notebook is maybe somewhere in between. But even if other interfaces manage to bridge the gap further, I doubt the spreadsheet metaphor is going to go away in the visible future. Pivot tables and the like are like COBOL and mainframes :-) The corporate world would die a sudden death if you were to eliminate it (another reason to always make sure you can run things locally).
