> Did it fail

13 years to get to v0.0.1 is a success? Look at how much progress Ladybird has made in a fraction of that time. Remember that these people are constantly starting rewrites of C and C++ projects (when they're not demanding others do it) in Rust "for safety" (and "oops it's MIT now"), even of ancient Unix utilities with minimal attack surfaces like the "date" command, yet when it comes to a browser rendering engine, which entails computationally-intensive, aggressively-optimized rendering of untrusted input--a massive attack surface, and the very thing for which Rust was supposedly designed--they somehow can't get the right combination of enough Rust zealots (and Adderall) to get past the finish line.
