It was a provocative comment, sure, but I wouldn't say unproductive: others asked why Lua is superior, and several people answered, myself included.

Heartily agree that the same basic argument would apply if Roblox had started with JS! Lua isn't so much better than JS that it would be worth scrapping collective centuries of labour over.

But given that it is the better language, in my not-so-humble opinion, why on Earth would they switch?

I think the only rational way to argue superiority of Javascript over Lua, is to point to aspects outside of the language itself: larger install base, more libraries, bigger, more vibrant community, better tooling, and so on.

But I prefer to call that the ecosystem, and can confidently say that Javascript, alas, has the superior ecosystem. A pity, because Lua is the superior language.
