&gt; Heck, go is billed as a systems language and it&#x27;s GC&#x27;ed! That would be crazy 20 years ago. Perhaps still a little crazy today, but far more feasible.<p>Not at all, I was introduced to Native Oberon around 20 years ago. It was a great OS used at ETHZ and many European universities. Specially the system 3 version with its gadgets framework.<p>Around the same time DEC&#x2F;Compaq had SPIN OS implemented in Modula-3, with POSIX API and a very interesting distributed objects framework.<p>Xerox PARC had the Mesa&#x2F;Cedar workstation in the early 80&#x27;s.<p>There were a few OSes implemented with Algol 68 variants that had GC at OS level in the early 70&#x27;s.<p>The craziness is that in the last 20 years, thanks to the rise of FOSS and its UNIX&#x2F;C culture, younger generations seem not to bother with everything else that existed.
