Infrastructure engineering manager in the company I work for: civil engineer, studies completed 1997. MBA 2003. That's it.
One example, and don't tell me it's an anomaly and a bad example
With implementation of BIM and more companies moving towards BIM the future of engineering is going to change, is busy chanfing, as well. Those who do not adapt, widen their field of knowledge and move towards information management is going to stay behind. Or course if you on your way to retirement, or not planning to grow in scale of what you do, similar with "IT" you can just carry on and eventually become background noise while the rest of the world moves "forward".
So yes, it is a good example, but again IT, the IT of engineering and architecture becomes a lot more important. As rules becomes strictor and engineers start do a lot more and work closer with other industries, working only with the knowledge you qualified with 93/97 you will quickly become a dinosour.
Of course if that is what you want, then that is okay, but your comment "stay away from IT unless you want to continue study" or something, says more about what you as a person want for yourself and not the ever changing world and move towards information technology and management in almost every industry.
With the advancement in software technologies and information management, Soon Architects and BIM modelers will take over most of what engineers do and just use them for signatures, unless they conform and want to do more than just scrap booking and site inspections.
Yes, I don't have a degree, but I continue to study and grow my knowledge.
Have not even touched on AI and algorithmic design.
