>But I think about all of it. nginx, haproxy, redis, postgresql, nodejs, python. I don't think I could even write out all of the open source I am using in my projects within the confines of a Hacker News comment. That seems contradictory to your opening sentence though, no?

Decisions like this will only accelerate it.
