Why Non‑Tech Folks Underestimate Software Development Time and What It Reveals About Our Brain

The article explores why outsiders consistently underestimate software development effort, explaining that humans rely on intuitive cues like speed and volume which work for physical tasks but fail for intangible code, and argues that only experience can reliably gauge software complexity, while unexpected bottlenecks further complicate estimates.
