Tinkering
The most recent episode of Mad Dogs & Englishmen1 starts off with a discussion of buying and assembling and AR-15 from scratch. It’s an interesting process, but the conversation took an even more interesting turn as they focused on the decline of a tinkering ethos in our society. The machines and devices we use are often too complex to repair, disassemble, or customize. If you open the hood of your car, you won’t be able to see or even access many of the most critical parts - you’ll most likely see a series of injection-molded plastic meant to not only protect but to discourage amateur tinkering.
