> You can also keep running Rails 3 for 20 more years if you want btw. While I understand your point, not on a modern OS you can't. You literally can't build the tools necessary to run it on a modern OS. I know because I've had to deal with this many many times. You literally are forced to run that stack on a version of ruby that's EOL and on an OS that's EOL. I mean yes, you CAN do that, just like you can run Windows Server 2000, but it's really really not a good idea.
