juliobiason, My cynical view of Python:
Python is going to die. Not today, not tomorrow, but it will not be a lasting language like C, C++ or Java.
The main issue is that Python is, right now, the front-end of C/C++: You want to generate statistics about something: Python has the libraries! -- but these libraries are in C++. Do you want to handle IA: Python has the libraries! -- but these libraries are also in C++.
If, sometime, the C++ committee wakes up and decide to clean up their act and make the language syntax simpler, Python would die.
"Oh, C++ will never be user friendly." Look at Java, compare its version 2 (e.g. Java 1.2) to the current language: It is astonishingly easier to use modern Java compared to the old ones. And that took something like 10 years.
It just takes someone wanting to create a library that it is really pretty and easy to read in C++ to completely obliterate Python.
