I find this attitude interesting. By the same reasoning why are .debs better than building from source, and the ultimate - horse drawn buggies vs automobiles.

I've seen containerized applications described as "statically linked apps", it's one blob with dependencies included. I'm moving in that direction (vs cap-style deployments) because it guarantees that all machines are identical (from QA to staging, to production). Spinning up additional machines becomes trivial.
