Try quitting and applying your knowledge to a separate field with significant growth trajectory and a lot of interesting subjects to learn about, such as industrial automation. Sometimes you just need to get back in touch with the curiosity and sense of challenge and wonder that goes with being a complete newbie in a new discipline. We are lucky that having a systems perspective and algorithmic analytical capacity means we transfer well to numerous complex disciplines. Many established fabrication operations are now seeking people from a computing background to assist with systems integration, operations planning and business-level investment trajectories. Get in there, learn and be valued. Feel free to email me for some pointers.
