>That neglects to consider the fact that you are now depending on orders of magnitude more code than before, which from an overall perspective certainly doesn't mean "less bugs", and in fact could even make things more difficult to debug. If you choose wisely your dependencies those are going to be a lot more reliable (incl. less bugs) than the code you can write in a few hours; because its code with tests, a large user base, etc.
