It does sound interesting, but I was mostly joking just to extend the copypasta.
I don't know enough about programming to know whether it's even suitable for writing a kernel. As far as I'm aware, Lua is mostly used for embedding scripts like in games, but the engines themselves are better written in C or Rust. I would assume a similar concept applies for writing a Kernel.
Perhaps it would have made more sense if I said Fortran or PS-Algol. It would have been more clear that it was a shitpost
