I'm sure that's some fun reading, but you're getting too much ahead of yourself, learn basic electronics first, play around with breadboards etc. Once you feel you really want to dive deep then start making common parts like 555 timer using discrete transistors, it will get you to understand what's going on under the hood of an IC.
Personally I would focus on the construction, it has actual money making potential. Electronics is basically a hobby at this point as you will never be able to get to a point that you can make a real living off it and compete with the big guys. Even the major electronic brands don't even make their own ICs or core components. Take TVs for example, there's a few dozen well known TV brands, but there's only like 1 company that makes the actual display panels.
