These modern systems are just extremely complex, created by the combined energy of many, many people. But nature around us is still even more complex, and there are many mechanisms in nature we don't understand (like the human brain). Therefore I don't understand why you consider the technical systems to be especially "hellish".

Even if you Mac is somehow "locked", you can still take an electron microscope to its mainboard and try to understand the circuits and so on. (In theory - in practice, I've just read a modern Ryzen chip consists of billions of transistors, so good luck trying to reverse engineer it).
