The first version of UNIX may have been created in 1969, but it continued to evolve for 20ish years, and I don't think 1969 UNIX really resembled what we had in 1989. But then the UNIX world stagnated, because Linux people were obsessed with cloning System V. Sometime during the Linux era, text became "cheap" enough to be used as a data format. So perhaps I'm wrong, and JSON's time has come in the UNIX world after all.
