Other languages?

I'm learning C++ now as my first language. Just started a few weeks ago and I'm doing quite well with some books and stuff but what other languages should I learn alongside C++? And are there lower level languages to C++ I could learn in the future that would still be useful?

Beginners should learn assembly.

If they started that low, and worked their way up, I'd see a lot less idiocy on a daily basis because there'd be some fundamental concept of what's being asked of the machine behind the scenes.
