I don't think it's a matter of respect. I think it's just the result of a simple cost-benefit analysis. It's costly to support additional runtimes in your application. That's why despite the popularity of many JS alternatives, none of them are natively supported by browsers. Chromium even has a branch with a native Dart runtime but Google's own web browser doesn't want to take on the added cost of supporting Google's own web scripting language[0]. > But, the factorio team didn't offer this to me, and I appreciate their diverse values, suggesting that Lua is adequate. I assume they didn't chose Lua because of the language syntax. I'm sure they chose it becaude it's a language intentionally designed to be easy to embed into other applications. Lua even describes itself as "lightweight" and "embeddable"[1].

I regard lua as essentially trivial to embed and to use to script a host application. The ease of hooking to/from the host application written in C is very straightforward and painless. Its possible to have lua call C which calls lua which could call C. That reentrancy is underrated but so very useful. The simple design also means you can have multiple independent lua interpreters with no overlap. Isolation is quite achieveable with no real effort. Just create a new lua state. Contrast this with python. Ouch. But python also supports embedding and can import C functions etc. Quite a bit more effort though. Multiple interpreters isn’t so nice. Not when you've experienced lua's ease of embedding. The GIL isn’t great either but not a big deal if everything about a script is in a single thread.
