Computing systems are built in layers. The text field that you used to write that comment has a rendering layer that was only universally present across devices and operating systems about 8 years ago.
We are now operating in an environment where the average programmer is writing using frameworks on top of frameworks, on top of libraries, on top of SDKs, on top of containers, on top of VMs, on top of OSs, on top of hypervisors, on top of kernels, on top of microcode, and that's collapsing a bunch of the layers.
To have any hope of explaining to the next generation how many of the truly beautiful and fun aspects of computing systems operate, you need to strip away many of these layers.
A great way to do that is with old systems where the layers didn't exist.
