Another one of the biggest uses of Lua outside the hyperscaler-type software like nginx or redis: Roblox. Soooo many kids run games on Roblox every day!

Roblox not only runs entirely on Lua, but they've been working on their own type inference version of Lua named Luau, and open sourced it, and it's still in very active development.
