I’d be interested to read the prequel to this
I used to be the almost-sole developer on a project. I watched myself writing inefficient spaghetti code. I watched myself unable to answer the question “how long will it take”. I watched myself stay at work until 2am to get things pushed out without tests (an effort that was lauded in front of the whole company). My own response was to spiral into self-loathing, but I can easily imagine why someone would conclude that the problem was with the world around them. If the world tells you that you are the chosen one who must save it, it might be your tragedy to believe it.
