As we know, everything is broken.
Most of the stuff is broken in known ways to a terrible degree. Usability sucks. You can literally see the brokenness. Most of the stuff does not work properly, is slow, insecure and just stupid. It does not do what it is supposed to do, at least not without risking you harm.
Some stuff is a little bit better and only broken in more subtle ways. Some edge cases might not work. Some obscure security holes might be in there.
Then there is some very rare stuff, which has exceptional quality. But even then, we all know it probably is still technically broken. On the unlikely chance that the thing actually works and no mistakes were made, there is certainly a bug deep down in the Kernel or somewhere in the CPU.
You take some of the very rare stuff of exceptional quality. Does it do all the things you want it to do? Probably not. So at best it somewhat works, does most of the things you want it to do and only has unkown brokenness, hopefully very deep down and hidden away as far as possible.
Now comes the biggest problem: Even if you choose the least broken stuff, you know have to start maintaining it. Things below it will start changing and reintroduce more brokenness. By using it, you sign up to fight it.
Now I have this superpower to actually fight it. I make things less broken. But I am fighting an ongoing avalanche of brokenness. My day has 24 hours, I need to sleep some of them and the avalanche just keeps coming. Some days I like the amount I have shovelled away. Some days are ending with me still up to me neck inside it.
I am not like Sisyphos, other people are using the space where I shovelled most of the brokenness away. So it does make sense and is fullfilling. I have fun, when I look at a small area, where the brokenness will stay away for some time, even though I know, it will come back at some point.
I am not immortal. I can probably do this for another 50 years. So 50 more years of shovelling but vast mountain chains all around me.
So I have to be very careful to only pick the most precious areas to clear.
