Earlier quoted context omitted.
Not really. There is an ancient curses-based spreadsheet program called "sc" (spreadsheet calculator). It sounds like "scim" is to "sc" vaguely like "vim" is to "vi": new program with more features cloning/imitating ancient program. "vi" was written by Bill Joy in 1979. "sc" by James Gosling in 1981. sc-im claims to be based on "sc". It's a direct lineage unrelated to GUI spreadsheets.
Gosling wrote sc? I had no idea. I was an scim user before moving to visidata like another poster mentioned, so I kinda-sorta feel like an sc user. For those who don't know, James Gosling invented a popular VM-based "write once, test everywhere" programming language named after a tree. Then named after a coffee.
