Actually I've seen very similar things happen in practise. "Horror scenarios" happen all the time. Look, you can sing the "works for me!" song all you like. The fact is, you are years out of date and this is very bad practise. You will: - have trouble even installing a compatible environment from scratch - have trouble searching for information on issues you encounter - have trouble hiring anyone good to work with your decidedly legacy code With a fast moving platform like rails, you allow yourself to fall years behind the mainstream to your sorrow. It's like keeping backups. Yeah, you're fine without them, until the "horror scenario".
