I don’t know about game dev, buy SerenityOS guys are flirting with Swift.
If it wasn’t from Apple, I would be all over it. They basically took different languages and most of C++ devs made fastest advance in Swift. Rust I do like and support, but is too confusing for amout of free time I have.
It is very hard, time consuming and boring to iron out those finishing issues in any software product. You need team of people being paid for that.
When doing it for fun, I just go until it works and until it is fun. As soon as I come to those last 20% I never touch it anymore.
So ai doubt it will happen until more companies start paying decelopera to do it. But I don’t see the business model in that, so I doubt it will get better fast.
