You're hand waving, and there was no flaw in my thinking. C doesn't scare me and I use many languages, and that still has no bearing on the point of the conversation. C is a maintainability nightmare compared to lighter weight scripting languages. That fact stands on its own.
There are "C folk" who won't use anything else because they're stuck in the rut of only thinking of execution speed, pointing that out is not a flaw, it's a fact.
