Mostly opportunity. I find many problems in computing very interesting across diverse fields, despite the fact that I have a PhD (which usually implies close study of a very narrow area). Am an applied researcher: I can’t do pure theoretical work, but I can understand it in a knowledge domain, look at the problem and find the appropriate solution given existing knowledge, often developing new tech in bringing that idea or variant to life. I often borrow from completely different areas, including biology, which is a gold mine of elegant and efficient solutions. Phd means I often bring more rigour (better quantification/rationale/metrics) to the solution that quite frankly wasn’t possible before. I know I can’t develop quantum mechanics from scratch and am happy with this limitation. Would much rather use it to build a quantum drive anyways. Being happy with your limitations is crucial for personal happiness. And lots of sleep. It is needed.
