I no longer fear losing my job like I used to. I used to go in to work worried about deadlines, fearful of any call from my boss, worried that I might screw up and get fired.

I don't fear that. I don't feel that it's likely anymore. Fear has been replaced with contempt. I do not have empathy for my coworkers. If one of them were to get sick or injured, I'd have sympathy for them, but on a day to day basis I no longer see them as human beings. They are robots with different characteristics which I believe can be programmed. My project manager has a huge ego; my junior dev is hungry for promotion and status; my boss recently had a child and is desperate for interaction with anyone other than his family. Every time I talk with one of these people, I put on a different mask. I pretend to care about what they care about, I pretend like I can help them, or that I want to see them or the company succeed. I do not. My only goal is to collect a paycheck for as little interaction with these things as is possible. Each one is a server that I ssh into with different public keys. I manage their state via a set of well known scripts and commands, and I sign out. I no longer even turn my camera on during meetings. They have a physical image of me in their heads which is based on years-old pictures. I could shave my head or lose an eye or get gang tattoos on my face and they would never know. I spend my day talking with machines about how best to talk with machines
