I'm not sure I agree. I'd prefer working on a boring MVC software, being proud of it being reliable and having the time to work on features my customers will genuinely like rather than extinguishing fires every weeks and adding band-aids everywhere..
I am somewhat convinced that a not-insignificant portion of engineers is under-employed in an intellectual sense. When $BIGCO announces the release of a new tool that supposedly helps with their planet-scale needs, the engineer just lights up at the thought of needing to dig into a new challenge. (The impulse to grow is well and good!) It also helps that places like HN buzz with new tools, it is good resume material, and a vague feeling of not being left behind if said thing takes off.
The real fix is to get away from domains/companies that bore you in this way, but it is not an easy realization. There are a ton of interesting problem domains out there! I did this and am much happier with my career.
