> Python/C files didn't work in a vacuum They do if you use the standard library (which for python is quite extensive), and copy any dependencies into your own source, as if they are your own. By "in a vaccum" we can mean if python o is installed, it will work. > Capture all necessary dependencies Docker doesn't capture any dependencies. They still exist on the internet. It just captures a list of which ones to download when you build the image. Do you think software we write now has more longevity than older software that uses make or a shell script?
