Seeing the salaries now I kinda regret switching out, but the companies and business problems you get in Python & Java are much more interesting.
May be a personal taste thing but graphics programming, computer vision, scientific computing, robotics and even some embedded systems work is far from boring imo.
But certainly the above are niche fields in a market where software engineering is almost always limited to webdev.
It's gonna migrate away from C++ if C++ becomes "legacy."
Embedded systems work is perhaps the exception - since there will be old hardware in the field. But firmware parts go out of production within 2-10 years and so new drivers require creation and new features encourage a migration to a whole new system.
