Software is churn. Sticking to outdated versions for too long, the rest of the world evolves without you, until other things will start breaking. For example because a new dependency A you need depends on another package B you already have, but A needs a newer version of B than you use. At that point, you have a huge undertaking ahead of you that blocks productivity and comes with a lot of risk of inadvertently breaking something.

Whether someone else or I am the problem doesn’t matter to my customers at the end of the day, if I’m unable to ship a feature I’m at fault.
