If there's enough actual interest, some group of people will just clone the language in an open manner since enough is known about it. But that doesn't seem to be happening at the moment.
I thought Odin was one of the clone languages at the start (although later it diverged from Jai in many aspects, and is far ahead Jai in the aspect that it's open-source and is actually being used in production).
But really I would like Jai to take some time to mature over the years, instead of rushing out for an immediate public release. It has some very ambitious ideas that would absolutely be killer features, but I think it needs ample time to get polished. (Off to writing C++ code during the time then...)
Odin has similar syntax, but one of the main reasons I am interested in Jai is because it has strong meta-programming support[0], where as Odin doesn't and will likely never due to the author of the language not wanting to go in that direction.
Yeah, I have about the same opinions. Odin made a conscious decision to not invest much in compile-time metaprogramming, and as a result was able to actually ship things without spending too much time on language design. But it’s a bit less ambitious than what Jai was trying to do.
