There's two major production-ready Go-based operating system(-ish) projects: - Google's gVisor[1] (a re-implementation of a significant subset of the Linux syscall ABI for isolation, also mentioned in the article). - USBArmory's Tamago[2] (a single-threaded bare-metal Go runtime for SOCs). Both of these are security-focused with a clear trade off: sacrifice some performance for memory safety and excellent readability (and auditability). I feel like that's the sweet spot for low-level Go - projects that need memory safety but would rather trade some performance for simplicity. gVisor is a very fun project - they're really pushing the boundaries of what's possible in Go. Typical overhead is <10% thanks to a number of new features (systrap[3], directfs, in-process overlay...), all while maintaining a well-documented and super clean code base.
