> We've accepted specialization in most aspects of modern day society as a good thing. I fail to see, outside a small subset of programming, how you will always be able to write better code yourself for whatever domain you're working on.

It's strange that using fewer third-party dependencies has to be defended on a site called Hacker News.

Also, the code you NIH doesn't have to be superior to the third party code. It merely has to not get in the way for what you're doing. This is different from being "better," which has many dimensions to it. Example that comes to mind: I could reach for something like libuv, or I could just use POSIX for synchronization primitives. I'd prefer to the see the latter in most code unless there were explicit reasons for libuv, such as cross-platform support.
