I think what you say is true. Anyway, I do not need state-of-the-art technology in my case. Basically I really wanted, and I think (in order of importance, but being the two former points the most important with a big difference), this: 1. Concurrency support 2. Easy to bind into C++ 3. Familiarity, etc. Namely, if only Lua had existed and provided that Sol2 exists and makes it bind it to C++ easy, I would have chosen that. But since Wren + WrenBind17 existed, Wren had more familiar syntax and it was a viable choice, I went for that. I was trying to find the past of least resistance (lower learning curve, easier to bind, concurrency making my code easier, since I am familiar already with most patterns) As for ChaiScript, it was the first thing I took since it was so easy to embed. But it had its own problems: lack of concurrency and it does not point the file and line of errors, which is very painful because it drops your productivity. And scripting... scripting is about productivity, at least that is what I was using it for.
