Things getting more complex

I think the reason things keep getting more complex, is the same reason that Elvis and Michael Jackson died. Both of them had a personal doctor, with only one patient, and each doctor got bored doing nothing, and had to justify his existence by doing a lot of unnecessary and ultimately harmful stuff. That's what engineers (and managers and executives) of tech companies are doing. If they don't make upgrades, they feel useless, and I guess it's really hard to upgrade something without making it bigger or more complicated.

From Ran Prieur’s 075.
I think this is an important point I never thought about, as to why people contribute to the modern world. There is a type of person that simply doesn't know what else to do with their time, because they're paid to do certain things so they might as well make something that works well, expand, etc.
I don't think it is the main reason however, because there is also a major component of constraint, often times not explicitly but rather through removing the other options. You work within the modern world because there isn't any other real way you know of to make money, and then you're told that being an engineer pays well, so you go down that path, etc.
But to come back on the original point, it is pretty embarrassing to admit the extent to which I don't know how to handle extra free time. I guess you could say that it's the addiction of novelty and doing things, which is to say, the momentum of the mind which keeps spinning in circles and which overtakes your attention.
So in an important but also pretty hilarious way, a major skill to practice seems to be the ability of being fine with doing nothing. ³ Enough is enough, and often you just make things worse and worse by adding extra complexity. As Montaigne says:

There is nothing useless in nature; not even uselessness itself.
