Eons ago, I worked for Lotus Software (way before they belonged to IBM) on an exiting new product - their flagship Lotus 1-2-3 spreadsheet product, in those days the preeminent spreadsheet offering in the world, ported to the IBM mainframe.

I travelled around Europe as we sold this to large corporations who wanted the power of the spreadsheet, but multipled by a gazillion times and made multi-user.

Almost every customer was so receptive and excited, it was a fun and job and easy sell.

But later, we learnt that those customers were in fact the early adopters, and Lotus never did manage to cross the chasm with that product. Later Microsoft produced Excel and..well the rest is history.

My conclusion: the world doesn't need a better spreadsheet. Existing spreadsheet technologies are good enough for the hokey, half-baked things that people like to build with them.
