Are You Paying for Reliability or Hype in the Age of Vibe-Coding and SaaS Subscriptions?

In 2026, many engineering teams are coming to terms with an odd new reality: a growing percentage of their codebase wasn’t written by their own team… or even a human, for that matter.

Rather than being pair-programmed, reviewed, tested, or even fully understood, it was AI-generated. Confidently, instantly, and sometimes a little chaotically, by something that simply “felt” like the code would work. In other words, it operates off vibes, not knowledge.
