Programming Language to Replace C++

I think we can all agree that C++ is a terrible language. So why is it still around?

When talking to most C++ users (game developers, systems programmers), I've found that most seem to recognize C++'s faults, but they don't really care. They aren't even the slightest bit interested in a new language that might solve its problems, even one that gives them all the power of C++ with none of the downsides. You can't even get them to look at something new.

Why is that? Why does everyone just 'live with it' without wanting to improve the situation?

There isn't much point when:
1) We're already familiar with it - faults and all - our systems are mostly complete and working in C++
2) It's well entrenched with libraries
3) newbies everywhere have a superficial understanding of C++

Why bother with exotic new languages when we have to take effort to learn a new paradigm. If the new language is already similar to C++, why learn it when we could stick with C++.

P.S. My favourite language is Haskell and esolang is Grass.
