Not just that, but the longer you wait the more you diverge from mainline. The more you diverge, the more painful re-integration will be. By updating all the time you can address bugs and changes as simple fixes here and there. Wait too long and you run the risk of having a really painful merge/update cycle, most likely happening under duress because now you have to update because of some bug fix or security issue. The more dependencies you have, the more critical it is to stay up-to-date, and thus this directly leads to all the craziness with NPM based projects whenever something goes wrong.
