I think the author is basically diluting the term "technical debt" to the point it becomes meaningless. Much of what they are talking about is the inherent difficulty of managing complexity, mixed with the difficulty of understanding requirements/defining features well.
I think "technical debt" as a term is overused and sometimes misapplied, but the core idea resonates with many developers, at least the way it is most often used - which isn't exactly the original proposal as another commentpoints out. The key part of it is the analogy with an interest rate. I can decide do put 5k on the credit card for a last minute holiday, but for as long as I don't pay that off, I'm paying 20-something percent, every month, forever. Similarly for example a rush to add features to hit a demo deadline can introduce brittleness and abstraction failures into your codebase that you pay for every time you make changes, add features, do nearly anything. The analogy is that some of your development is going to be wasted "servicing the debt" going forward until you fix that (pay off the debt). That doesn't mean its the wrong move, for the same reasons that taking on debt can be the right move for a person or business.
