Indeed. As an example, modern era devs don't realize how much of the global financial system is underpinned by decades old Cobol code. Personally I'd rather be working on a system that's massively important with less flashy tech, than building more inconsequential apps with the latest frameworks.

I am the same type of person. Solving a problem and creating a great product can be very rewarding and is my primary motivation.
There have been times in my career where I have been thinking more about how I could sneak in a new technology in a project. In those cases it was a sign that the things I worked on were not motivating enough, or a bad work environment. I'm more aware of how these things affect me now that I have the benefit of hindsight.
