> for learning.

That's great if that's what you want, but you are commenting in a thread full of people gleefully spouting off about decades-old installations that they self-admittedly have “no idea” how to upgrade. Most people in here would be better off if they admitted to themselves that they are not actually taking advantage of the opportunity to learn, and are instead undertaking a liability.

In this framing, learning is always a liability. The real issue is undertaking the liability while not capitalizing on the opportunity it presents.

The “liability” I refer to is that of wilfully, knowingly leaving a system unpatched in order to avoid the learning opportunity of upgrading it.

We're working toward the same goal here, yes.
