Lua's very small by today's standards but it's huge compared to the languages being discussed here. Computers like the Altair 680 discussed here only had 1KB of ROM which is orders of magnitude away from being able to support Lua. Lua's minimum size is about 63KB. The "tiny" languages being discussed here are really, really tiny, and are also very limited in their capabilities compared to a language like Lua.
