Perhaps. But it's rare that an industry just sits around and stagnates to the extent that 20+ year old knowledge is applicable to current day problems. Even in the graphics industry, 20 years ago we were still discovering perspective correction and shaders were but a pipe dream. The problem set keeps evolving, and the tools we use to solve those problems keep evolving as well. Handwritten HTML -> vanilla JS -> jQuery -> Angular -> React, etc. It's not just the languages, it's major paradigm shifts in solving problems. If you want to get out of that rat race, then jump on the management track and stay there. Even then, though, you need some familiarity with what your team will be working on.
