Not necessarily and most likely not. I think a lot of people's definition of "fixed" is "stop hiccuping in the previous way so that my butt is covered" and not "yes, it actually works and was given the proper time and testing to ensure that remains true."

Developers would do well to remove the word fast from their vocabulary. It has done tremendous damage to human systems (and the mental well-being of the people dependent on those systems). The whole reason the "technical debt" exists is because there's an addiction to speed. The sad part is that when you poke at that with most people, they couldn't give you a clear reason as to why they need to move fast; just that they have a sense that it's "how everyone does it."
