Typing characters is maybe 1% of the job. The other 99% is understanding how the change affects everything else. Changing a single line of code in a function called by 1000 other functions each themselves called in 10 other functions can still potentially be more work and a bigger change than changing 9000 lines of code in a function called once.
If we don’t learn, then WTF are we doing with ourselves. The human existence is the pursuit of knowledge. The only depressing thing here, IMO, is the idea that living out a life as grazing cattle, concerned with nothing more than gorging oneself with the next meal is the only reason to live.
Comfortable? Sure. Self-actualized? Not a chance. There’s more to life than living out only the most basic biological needs.
