You take that linked xkcd far too seriously. Life is not about maximising productivity. We can also save time by not caring about the color of our clothes, getting cheap fast food instead of preparing our own meals and so on, yet in the end most people don't do that because the difference is more than hours of their life. I got better ergonomics, fewer distractions and higher comfort out of my customisation. Yes, I sunk many hours to get to that point. But on the way I learned many fascinating concepts, bash scripting, a deeper understanding of software and computers and more. Without this kind of tinkering I wouldn't even have started programming in the first place.
