Programming language designed to prevent security issues from occurring?

I’m working on creating a new programming language and trying to find that first niche to tailor it to. Would you appreciate a programming language that would make it as easy as possible to encrypt & salt all information stored in databases & files and sent over the network, etc?

I already have it so that it’s as fast as C++ but guaranteed to be memory and thread-safe without the programmer having to think twice about it.

The idea is that you write it quickly and productively and don’t have to think about the security, because it’s already baked into the end product.
