> Unix was written in C because Thompson and Ritchie had been working on Multics, which was written in PL/1 in the 1960s. So the idea of an OS written in a high level language was hardly obscure and had nothing to do with C.
OK, but at the time they started working on Unix, Multics had not yet been delivered. Nor was it clear that it would ever be delivered. So the idea that an OS could be successfully written in a high-level language was not yet proven.
