One of the greatest personal flaws your average engineer has (I can say this because I fall in this category), is the constant desire to do more engineering. We have a need to make newer, cleverer stuff ad infinitum, whether or not it's needed, whether or not it's even useful. This is why there are so many frameworks, this is why people make their systems scalable before they need to be and bloated beyond their use case. We like shiny toys and we like to use them to make more shiny toys. It's hard to be someone with that mentality when most of the major problems in your field are pretty much already solved.
