With over 20 years working with Java, I'd much prefer working on Python for lots of reasons, but a big one is that the kinds of projects that involve Java are always involve the same stupid politics and organizational struggles. I've noticed that projects involving Python are way more enjoyable with less friction, likely due to the organizations themselves being more open-minded and maybe younger. I don't know. At some point, every Java project at every Fortune 500 company I worked with was the same damn hellish mess and I had to get away from that.
