I suspect you meant that sarcastically, but if system software (meaning OS kernels, network stacks, device drivers, etc.) were written in better languages, our computer systems could be far safer and more robust, quality of life could be better, and the benefit to productivity and the global economy could be substantial.
For the computing industry, it is one of the great tragedies of our time that C and its derivatives have become so entrenched. There is absolutely no reason we can't have a systems programming language that offers the necessary low-level control without the limited programming model, error-prone syntax and weak safety features of C.
Unfortunately, it is momentum and ubiquity that keep most of the industry using C and its brethren, not technical merit. The vast ecosystem surrounding C is hard to beat for scale. There is promising work being done in some places, Rust for example, but I know of no practical alternative that is ready for production use today.
Of course, OpenSSL itself isn't running at the level of an OS kernel, so it doesn't need the same degree of low-level access anyway. But there is a wider point here about much more than just OpenSSL.
