Whatever language you end up choosing, I hope it will be a memory safe one. Browsers' main purpose is to interact with the outside world, and they even have to run third party code (JS) all the time, so minimizing attack surface would go a long way I think
My favorite type of discussion! Language choice would seem super important long, long term and could provide long run advantage over other engines. Given the goals and philosophy of Ladybird zig seems like a complementary choice, and headed in the same direction in terms of community and freedom. And Perhaps just a sprinkle of something more verifiable than zig on the edges where correctness and safety are super critical. Have a look into tigerbeatle (https://github.com/tigerbeetle/tigerbeetle/blob/main/docs/TI...) and their philosophy.
