Neat! But if we're sticking to the source code analogy, the matrix multiplier probably maps closer to a CPU or an interpreter - I wouldn't say every Java program is open source because you have an open-source JVM.
Yes, which is why if you're serious you will exclusively use the terminal to protect your computer from even the passing chance of being exposed to a so called "image file".
In all seriousness, compilation and model training are lossy processes and erase a lot of the context needed to understand the output (and with model training we don't fully understand it even with access to the training data). Images aren't necessarily derivative of anything, so the analogy breaks down here.
often images are not only lossily compressed, but they are a composite of many images/layers/image transformations. these are lost when the image is flattened and then distributed.
