To be fair, 50 years ago security wasn't as proeminent as today. (Telnet anyone?) Even the way to write C is not the same as 10 years ago. But habits are hard to change. Forcing a change by changing the language is effective. Also, having languages that do more checks is also an option, but has performance impacts. In the end, the weakest link is always the coder. Much more nowadays as they are asked to emit feature faster and faster.
