The main reason comes from how we were taught to write programs. It is the same problem with human languages: if you learn to speak English as a kid, you'll hardly have the need to learn German. Going from something like Python to Forth is similar to learning a foreign language, the way things are expressed in Forth are sometimes radically different. So you need to relearn to program, which is a painful and expensive process for companies. The languages that become successful are a direct translation of the first successful programming languages like Fortran and C. Everything else is too alien to succeed.
