I was only tangentially involved in X, but was active in a lot of related projects (some Gtk infrastructure, Ghostscript, the seeds of what became Inkscape), and now work on GPU-accelerated font rendering. I also played a central role in getting Rust adopted at Google, and now one of my passions is advancing the Rust GUI space, as I feel like that has enormous potential.
Honestly there were so many small signs that you work at Google, e.g. the fact that you used Bazel and Blaze interchangeably or referring to Carbon as a C++ replacement, although I guess both things are kind of public knowledge anyway...
