The pace is certainly different but I’ve found most engineers lose those skills that aren’t directly relevant to their job at hand. Ask that power plant engineer to do fluid dynamics and they’d likely be lost. The physical engineering disciplines are often hyper-specialized as well
Sure you forget but if you come into a fluid dynamic problem, you know that the universe didn't move to a new paradigm, I assume it's a different feeling to know that you can revisit the knowledge instead of navigating a totally new structure.
