Technical debt is normal and useful — it buys you time. The real danger is not paying it back regularly. A few hours per week prevent the total rewrite, which costs 8 to 12 months of development and often solves nothing.
We call it 'debt.' The word isn't chosen by accident — and it's the best thing that ever happened to it. Because like financial debt, technical debt is not inherently bad. It buys you time. It lets you ship faster. It lets you test a market before having the perfect architecture. The problem isn't having debt — it's not paying it back. And in the age of vibe coding, where code is generated faster than it's understood, this repayment discipline has never been more critical. After 15+ years working on production systems, I have never seen a living product without technical debt. But I have seen products die because their debt became unmanageable.
What is technical debt, really?
The concept comes from Ward Cunningham in 1992 — long before the AI era. The idea is simple: when you take a technical shortcut to ship faster, you take on debt. Like a bank loan, this debt accrues interest: every time you touch the affected code, you pay a surcharge in time, bugs, and frustration. A production product with zero debt is a product with zero customers. Because if you have customers, you have deadlines. And if you have deadlines, you've made compromises. The developer who has never shipped imperfect code to production has never truly shipped. The problem isn't the compromise — it's forgetting about it. Technical debt becomes toxic when nobody knows it exists, nobody measures it, and nobody plans to pay it back.
Vibe coding accelerates everything — including debt
In 2026, with generative AI tools, a developer can produce in one day what used to take a week. It's a productivity revolution. It's also a technical debt machine. Vibe coding — the practice of generating code via prompts without always understanding every line — produces code that works. Usually. But this code has predictable characteristics: inconsistent patterns across files, unnecessary dependencies, subtle duplication, and above all a lack of architectural vision. Each prompt solves a local problem without considering the overall system. The result: debt accumulates at an unprecedented pace. What used to take months to become problematic can now happen in a few sprints. The speed of code generation has exploded — but the speed of code comprehension hasn't changed. And it's this asymmetry that makes repayment discipline more critical than ever.
The total rewrite: the classic trap

Pay it back regularly: the only strategy that works
The right approach is continuous repayment. Not a refactoring sprint every six months — a few hours every week, non-negotiable. Here's how to structure it. Identify the debt: systematic code reviews, cyclomatic complexity metrics, increasing build times, declining test coverage, and most importantly — listen to your developers. When a dev says 'this part of the code scares me,' that's a signal. Prioritize wisely: not all debt is equal. Debt that blocks future features is urgent. Debt that's 'just ugly' can wait. The right criterion: 'Will this debt cost me more tomorrow than today?' If yes, pay it back now. Ritualize repayment: block dedicated time in every sprint. Not a 'we'll see if we have time' — a firm commitment. 10 to 20% of team capacity is a good ratio. Convince the PO: the product owner wants features, not refactoring. The argument that works: 'Paying back this debt now means delivering the next feature twice as fast. Not paying it back means stopping everything in six months for a rewrite.' POs understand business risk — speak their language.
Warning signs you shouldn't ignore
How do you know if your technical debt is becoming critical? Here are the signals I consistently observe with my clients. Implementation time explodes. A feature that should have taken two days takes ten. Estimates are systematically exceeded. This isn't a skills problem — it's debt weighing down every change. Cascading bugs. You fix one bug, two more appear. The code is so coupled that a change here breaks something over there. This is a sign the architecture no longer holds. Onboarding is painful. A new developer takes weeks to become productive. Documentation is nonexistent or outdated. The code doesn't explain itself. The team avoids certain areas. There are files nobody wants to touch. Modules that 'work, so we don't touch them.' This fear is the most dangerous symptom — it means debt has reached a point where regression risk is uncontrollable. Turnover increases. Good developers don't stay on a codebase that frustrates them daily. If your devs leave citing 'code quality' in their exit interview, your technical debt is costing you in recruitment too. If you recognize three or more of these signals, it's no longer about maintenance — it's about a structured repayment plan before a rewrite becomes your only option.
Technical debt isn't a failure — it's a lever. Every living project has it, and that's normal. The real challenge isn't avoiding it, it's managing it like an asset: measuring it, prioritizing it, paying it back regularly. A few hours per week today prevent months of rewrites tomorrow. And in a world where vibe coding enables code generation at unprecedented speed, this discipline is no longer optional — it's what separates teams that ship from teams that stall.
