When I was young, a massive old upright board tipped over in an old building and actually came down, rusty nail first, on my head. It hit a low horizontal beam I was standing next to and was stopped/deflected just enough that the nail only poked a small scratch in my scalp.
Kind of hard to describe, but I imagine I would not have survived that even without the nail. Still, the nail was just kind of icing on the already massively incredible event chain cake.
Well, you could make one out of polycarbonate. Even PE or PA would probably put up a good fight before you could claim it's (non technically) shattered.
In practice? Constantly changing hardware with soc vendors that publish nothing and device manufacturers that (have to) keep pushing out new models on a short cycle. Plus many of them have extra shenanigans to keep the bootloader locked so you can't install a recovery (presuming you had a working one) so you could replace the os. There are some rare exceptions, but the hardware is rare and tedious and not many people can or will work on installable Linux on them.
If you just want to run some Linux userland, there's ways to do that on top of android, though. Want to get to a Linux like system or run a program? Might be as close as installing a terminal or running adb shell.
Well, in my time on the net, I've been sorted in the Geeks bearing GIFs and Programmer with a screwdriver categories before. But since I've done this a thousand times, intoxicated, without safety guards or PPE, I'm not really sure which way I'm heading now.
