It can be fun to look at the various "achievements" or things that are generally possible for determined people (no geniuses allowed).

CPU just happens to be one of them. Fascinating that such a seemingly complex marvel of innovation is just something that everyone can do.

Of course, there's lots of groundwork and you need to know "the trick" (eg. that you can use transistors to make computation machines)... but it's easily within your grasp.
