Which, despite being much younger and 80% made by one guy, is somehow way farther along than Servo. Ladybird doesn't have any pre-built images, but it's downright usable.

Andreas is incredible but that's an overstatement.

Still a monumental feat but don't downplay the community that's rallied behind him.

It's not further along when you consider the vulnerabilities that are present. C++ is unfit for long term use because it is intentionally introducing severe tech debt that we mistakenly imagine doesn't have to be repaid.

I thought Jakt was supposed to be memory safe (but it was very wip last I looked at Jakt)

Ladybird is written in C++

It is for now, but as both Ladybird and Jakt are SerenityOS projects, eventually parts of Ladybird might get written in Jakt. Jakt compiles to C++ and plans to have features like "inline C++" to allow easy interop between the two, so I assume they are thinking about this.
