After working with Ruby for some time, I realized that many co-developers don't have a slightest of a clue what they're doing with the language yet they do just about right with it - with C++ similar (careless) mindset and skill level would very soon end up in a terminated project.

In the end it's the domain which matters more than the languages - as I implied in my earlier comment, I outright require as much control over the hardware as possible - there are no alternatives for me. Rust comes close(and it's nice, I like it thus far!), but let's see in a few years.
