Web browsers must be some of the most demanding applications to develop: they have to do very many different things; they must be very efficient; they must be very reliable; requirements change very rapidly. If claims made by certain language X apologists are to be believed, one can infer that language X should permit developing a web browser in shorter time than C++, with performance within say 20% of C++ (or even superior to C++, depending on X and the apologist), with fewer bugs, and with a more maintainable codebase as the result. Actually delivering such a web browser would be a rather more convincing argument than empty talk or even glorified Fibonacci programs. Hence, I'm very much looking forward to future progress by the Rust guys.
