The complexity is thus: imagine you are presented with a 2020 laptop running on a chinese SoC, and you want to implement linux from ground up - empty repository. linux does not exist, and none of the hardware is described anywhere, there is no open source or easily hackable code out there for operating any of the hardware peripherals, nothing follows any standards. Also the laptop is actually 15 laptops, networked, and each of them has about 20 peripherals connected to it, all of which have to work at all times, or the whole machine grounds to a halt and worst case scenario kills you and then explodes. If that doesn't explain it's impossible, idk what can.
