Tech debt is like any other kind of debt: a way to increase leverage.
Some tech debt is like a mortgage. You get significant value, immediately, and can keep the payments manageable.
Some tech debt is like a payday loan. You get ahead by days, but behind by weeks.
Some tech debt is like margin trading. You make an educated bet about the future and if you're right, you've multiplied your success, but if you're wrong you've multiplied your failure.
There's a time and a place for each kind of debt, but taking on debt in a haphazard fashion can get you into a situation where you need to chose between putting an inordinate amount of effort into paying off the "interest", declaring bankruptcy, or risk having the "repo agent" come calling when you least expect it.
(And note that even "tech bankruptcy" isn't necessarily a bad thing, if you can do so in a way that limits the blast radius.)
