Having a bit of trouble understanding what the potential solution is and what problem it solves. I may very well have missed it in There but figured I’d mention because others may have similar thoughts. So, what problem is this trying to solve?
Same for me. From what I understood you want to say that "people love spreadsheets" but "spreadsheets have limitations" (e.g. they have weak/no data schemas). If this understanding is correct then it would be helpful to see a practical example where said spreadsheet limitations become a problem and how your solution overcomes this problem.
Any plans to add support for datahike or Crux? Datomic is not exactly cheap.
