Spreadsheets are kind of interesting tech. Because the user is more-or-less directly building the data dependency graph, I’d expect them to map better to actual hardware (massively parallel in so many dimensions) better than a sequential procedural language like C.

But, they are not very fashionable.

It would be fun to have a pipeline to compile a spreadsheet, that produces an executable. Potential outputs: cpu, gpu, fpga. Haha.
