C++ is designed to compile to the most efficient machine code possible. All
other considerations, such as programmer comfort, are secondary.

Ruby is interpreted, which means it can change anything about its situation
at runtime. That makes programming super-easy, and execution a little slow.

For example, there is no C++ eval("") function. You cannot load a string
full of C++, evaluate it, and have it change C++'s context.

The top level of a program should be only command-and-control code, which
uses short loops and few hard algorithms. Write this in Ruby, and write the
lower layer in C++, for speed:

The first images shows Ruby in the left panel, and C++, C, Qt, and OpenGL in
the right. You edit the Ruby code, and the program passes it into eval() to
change the shape on the right.

You should prefer to learn many languages, and then pick the right one for
each job. You are not getting married to Ruby.
