This is a gem observation from this thread. In my own tech sphere the first thing developers are talking about with each other is the new x,y,z lib or framework they're using to accomplish something relatively banal. There's still a lot of work out there that really boils down to basic CRUD and reporting at the end of the day, and developers naturally begin to invent complexities on top of that CRUD to make the work interesting and challenging. I'm absolutely guilty of this first hand.
I've found personally it also doesn't help that past work on projects e.g. large Rails apps that were never architected well turn out to be such nightmares to work on. The memory of the end state of these projects lingers with developers as they move onto the next piece of work, and they're inclined to say "no that doesn't work" and pick up shiny new-tech to do the old job instead.
As a side analogy: most small business construction jobs, e.g. building a timber frame house, don't involve the builders arriving on site and are stumped by the challenge of how to put up the framing for the bedroom walls - there's also very little challenge in these projects, yet the reward is in the completion.
