It’s basically “using Excel as a terminal for a shell”.

Haven’t watched the video yet, but in theory you can do anything in Excel on Windows since it can load COM/ActiveX components written in C / C++ / whatever language you want.

It’s not just mimicking Linux tho. It’s running an RISC-V emulator via an DLL that is capable of running a (more or less) full-fledged Linux image.

I want to see someone run Linux on a Turing-complete deck of MTG cards.
