But they don't care - instead, they just start a new one and repeat the process all over again.
The mistake here - made not just by the devs complaining about tech debt, but also by all of the company's customers - is that the goal is to produce something of value. It's not. It's to produce something promising to be of value at some point in the future, getting as many people as possible, as fast as possible, to buy into that promise (and stringing the paying users, if any, along for as long as possible), and then jettisoning the whole thing once it's past its peak, escaping with riches, to do it all again, or finally go FIRE.
