I learned electronics as a kid by messing around with old radios that were easy to tamper with because they were designed to be fixed.

The story I tell about how I ended up working in information technology is about having a computer all my life as a child, breaking it, and most importantly knowing that I had to fix it before my parents found that I had. The typical takeaway is that I was intelligent, talented, etc. But, really that reveals the wrong assumption.
More correct takeaway is by this point in computer history, peopleÂ designed computers to be fixed. The above quote suggestsÂ radiosÂ were initially custom built, which made them expensive to fix. To accomplish mass production, modular components make it easier to assemble but also as a side benefit easy to swapÂ failed parts. Computers followed the same path but not only on the hardware side but the also software. Modularity to softwareÂ is how we can patch, install new software, change settings, etc to fix issues.
Even today, I see people look appalled that smartphones can be successfully sold without an easy way for the owner to replace the battery or a microSD slot to add storage. We like to be able to fix our stuff. Maybe it is our Do-It-Yourself cultural biases at play.
Making things fixable lowers the bar to tinker with it. Tinkerability makes something more accessible to learn where, when, how, why it behaves the way it does. Those experiences in turn make a user self-taught into a power user and eventually into a computer administrator who really is just a power user given the keys to offlimits parts.
