Maybe
I think currently there's no plan for it. Maybe after they finish servo to the degree where it supports all modern html features

I have less hope for the widespread adoption of OS kernels written in safer languages - given the general unwillingness to even use C++ there (although plenty of toy/'research' kernels in safer languages do exist.) Although maybe we'll see one within the next century? Perhaps a microkernel for use in containers?
Of course, that still leaves bugs in the JITs, compilers, hardware, 'legacy' native interop, unsafe{} blocks, ...
