Exactly. I immediately thought, “So, we’ve invented VisiCalc all over again.”

TBF, VisiCalc is not open source, and this is relatively fresh start, so I don't think it's fair to compare this to a reinvention.

Isn’t that what reinvention means?

I suppose that's fair, and I concede, though I think you can play with the definition enough to make anything spreadsheet (even GUIs and webapps) be "reinvention" of visicalc, so I think the term is actually pretty meaningless.

My point was, it's a spreadsheet in a term window. That's basically what VisiCalc was in the 80s.

Appreciate the clarification, and sorry, I wasn't trying to be a pedantic pain in the ass :-)

No worries; all good.
