So someone who wrote their own functional operating system and browser from scratch which he is now targeting the public with, is not comfortable learning something new?

You are all assuming that the project will be c++ only when the authors haven’t said anything about the matter. Who knows if they aren’t open to moving to rust? The project is originally in c++, not only but, because that’s what the target OS supported. There are examples of other browser moving from c++ to rust (Firefox) who says they can’t do the same?

Let’s be honest, we both were childish :)

English is not my first language. I saw the mistake and left it here. You fixated on that simple mistake instead of answering the main point

I’m not sure 10 years old are allowed on the internet. Isn’t it time for Coco and bed?

I agree that Rust would be an interesting choice for this project but there’s a reason why this particular project is done in C++
