Most of my Python/Ruby stuff requires additional packages to be installed and so would need to be bundled anyway if I wanted it to be easily transferred to a vanilla machine so I don’t see what the big deal is. I got into programming through wanting to automate something really boring with AppleScript and I got into Ruby (wow that was amazing compared to AppleScript) through wanting to program sketch-up which has a bundled interpreter. When I wanted to use Ruby for other cool stuff, the Ruby website recommended I installed my own so it didn’t mess with the system install. I doubt there are very many people who get into programming by accidentally typing Ruby at the command prompt. Most will come to it via a the getting started page for the language they are interested in or because it’s bundled with the software they use for their job.
