Hi, I'm the author! Thanks for saying it's well made :).

I actually agree with you, the intended audience isn't someone who has never heard of CPUs before.

I tend to either write for myself: you know the saying you don't understand something until you try to explain. Or I'm writing for the person self-studying that is looking for that one explanation where everything finally clicks. I always get a lot out of those type of posts myself, so like to create them for others too.

You could use colors in the step-by-step simulation to show dependencies. Also show some tooltips/comments when things happen (that you described above). Ideally one should press next next next in the simulation, and understand what happens better than the paragraph description above.
