When faced with writing a distributed systems application at Bell Labs, and having to deal with C, the very first step was to create C with Classes.
Also had C++ not been invented, or C gone into an history footnote, so what, there would be other programming languages to chose from.
Lets not put programming languages into some kind of worshiping sanctuary.
Which then again, isn't that much of a deal, industry would have steered into other programming languages and operating systems.
Overall that would be a much preferable alternative timeline, assuming security would be taken more seriously, as it has taken 45 years since C.A.R Hoare Turing award speech and Morris worm, and only after companies and government started to feel the monetary pain of their decisions.
History would certainly have taken a different path when AT&T was allowed to profit from Bell Labs work, as their attempts to later regain control from UNIX prove.
Unfortunately that seems the majority opinion on WG14, only changed thanks to government and industry pressure.
Then we have the free beer UNIX clones as well.
Those industry members of WG14 don't seem to have done much security wise language improvement during the last 50 years.
