It is to be honest. I checked out various OS's and being involved in one of them ( Redox OS ). The problem is that this is "just" the OS part. There are multiple layers above and multiple layers below. Understanding the ins and outs of modern processors (pipelining, branch prediction etc.) motherboards pcie, things like coreboot, modern RAM etc. multiple layers of software abstractions until chrome or firefox have rendered the pixels i command with the javascript engine ... that is just humongous compared to a simple 6502 setup where i am able to really understand every aspect, can replace pieces, build things on top (hard and software) .. making my own RAM ... just for fun. Its a different kind of thing.
