Early in my time at the university I started to feel again the way the author describes. When I started to attend local tech meetups and started to take university CS classes out of interest, I started to feel rejuvenated. About 3 years ago, I changed to a team of much younger developers. They used modern tools, had less bureaucracy, and developed distributed applications, which I had little experience with. That was the step I needed to get excited about development again. Now I'm working extra time on my own because I enjoy the work. I'm also taking up niche areas, like language design, in my personal time.
To anyone reading this who might feel the way the author does, I give the advice to focus on finding your cultural fit and figure out the priority of your values. When I worked for startup companies I loved the absence of bureaucracy and the rapid adoption of new technology. But I hated having to wear a lot of hats: I really despise desktop configuration and system administration. My current team has some bureaucracy but we have teams to handle the things I dislike. So it's a compromise that I feel works in my favor.
