Spreadsheets IMHO are a solution space that hasn't been sufficiently explored. However they are not particularly visual (especially if you try to do complex things with them), they are very much domain specific they are extremely computationally inefficient, they're very hard to version and they become intractably complex much quicker than equivalent imperative or functional programs. I've thought about what could be done to improve on their weaknesses (like strong typing, bridging the gap to databases, better table naming), even wrote some code in this direction, but anything I can think of involves either making them less visual, less user friendly or both and doesn't even begin to address the lack of generality Finally I have to point out that some spreadsheets have been around for longer than many programming languages in current use so they don't actually lack maturity, yet they have seen little improvement in over a decade.
