Excel is an amazing tool, and if this becomes the Excel of the ML space then it will be a great success
I used to be violently anti spreadsheet but have come around to being amazed what people can do with a very limited subset of tools. So instead of looking down upon them (not saying that you are) I admire what non technical people that just want to automate something can do.
Also I think spreadsheets are better than half of the code I’ve ever written as it is easier to extend without having to delve into the guts of some impossible to understand language.
