AI pair programming
Also known as: AI pair programmer
What is AI pair programming?
Coding alongside an AI assistant that suggests, drafts and questions in real time, like a partner in traditional pair programming but always on hand. The human keeps direction and judgment. A controlled study found developers completed a task around 56 percent faster with an AI pair programmer, though the gain varies a lot with the task and the developer.
Why it matters
The risk here is not that the assistant is wrong. It is that it is right often enough to switch your brain off. A partner that suggests something usable on most keystrokes trains you to accept by reflex, and reflex is fine on a variable name and dangerous on a boundary condition. This is automation bias, the documented tendency to defer to a confident machine, and it bites hardest exactly where the code matters most. The value is real when the human stays the senior partner: taking the good suggestions, questioning the odd ones, and reading anything that touches money, security or data as if a junior had written it. Treated as an oracle rather than a colleague, it speeds you towards mistakes you would have caught yourself.
In practice
Halfway through an afternoon, a developer realises they have been tabbing through completions without really reading them, accepting whatever looked close. Two of those accepted lines turn out to swallow an error the old code used to surface. The habit that works is more boring: glance-and-accept for the trivial, deliberate read for anything with consequences. The tool did not cause the bug. Autopilot did.
