This holds the naive assumption that everything will be fine if you don’t touch the system.
But guess what:
- The dated libraries will bring security risks.
- The frameworks will be deprecated and not supported.
- System around evolves; newer systems won’t be compatible.
- Engineers won’t like to work in your system anymore.
If you still have questions, ask Kodak or BlackBerry.
