One of the reasons why I sometimes don't like the term "tech debt" is because you can take it on without knowing it. This is not true for financial debt. When you borrow money, even if you're not tracking it, the lender is 100% tracking the debt.
If you are in a team that discourages upgrading build systems, code reviews, code quality, testing etc there isn't really anyone that can point to instances where tech debt was accrued or how much there is.
