It's telling that your reasons for switching are all features of Python's ecosystem, not of the language itself. A lot of developers are moving to Python because of its libraries, and in many cases they don't care for the language at all.

That's causing a problem for Python: many of these developers who'd rather be using different languages seem to want to morph Python into their language of choice. The result is that the Python language is pulled in many different directions, and with each release gets increasingly bloated and strays further from its foundations.

Ruby, on the other hand, has a community that's mostly made up of people who actually like the language. That allows it to do a much better job of staying true to its core philosophy.
