Not universally true. Just find a manager who values successful delivery of project goals and is fine with "boring" i.e. tried-and-tested technology.

I blame Career-Driven Development for a lot of "shiny toy" (i.e. failed and complicated) projects.

Whether that's wrong is a deeper question - if it leads to better salary through job-hopping and promotions, despite a catalog of failures, is it actually the wrong approach from an individual engineer perspective?

I still say yes, FWIW; I enjoy seeing my projects succeed and thrive. But I know others may disagree.
