Just quoting this tweet.

I would like to make my apologies for defending M$, but I must from time to time. I have to put respect on github for handling the amount of shit code that has been added over the last 3 months. literally 10s of billions of lines of code that will never see the light of a CPU

It does a good job of describing something that I've been wondering. How many of those lines of code are written only to never ever run anywhere?
