Move fast and break things. The cicd model of delivery means that engineers are encourage to deliver functionality and polish things only if they are critical. The consequence is that people tend to reuse solutions of intermidiary problems no matter if those solutions are optimal. This accumulates technical debt that nobody really wants to repay because it is not a solution of a business requirement. Additionally, the Moor's law and the well-paid jobs of developers mean that the machines where the code is written are not the machines where it is ran with the difference often being a few generations of processors, graphic cards, and monitors.
