> I don't personally think there is magic in building a Docker container. Call me old-fashioned.

I still vividly remember setting up gcc in a docker container to cross compile custom firmware for my cannon camera and thinking about the amount of pain my local system would have been in if I had to do all the toolchain work in my host OS. Don't know if it felt like magic, but it sure didn't hurt like the alternative!

For sure. Docker is rad (sorry Docker!)... all I'm saying is that I am not proud of the fact that I can do it and I don't think it moves the awesome needle - but it's still hard to get right and a pain in the ass. It's just an example of something I appreciate that I can automate now.
