# How AI Agents Are Changing Software Work

## What is an AI software agent
An AI software agent is a program that can plan, write, test and deliver code on its own. You give it a goal in plain English and it works like a remote teammate. It opens files, runs commands, reads errors and tries again until the task is done.

## Why it matters now
Tools like Devin and Copilot agents already merge real pull requests at real companies. Benchmarks that measure real GitHub issues went from two percent solved to over seventy percent in two years. Most developers now use AI daily, but almost half say they do not fully trust the output.

## What engineers should do
Move up the loop: write clearer specs, review machine output carefully, and own the architecture decisions. The engineers who direct AI will out-earn the ones who compete with it. Verification skill is the new career moat.

## The bottom line
AI did not replace software engineers. It changed what an engineer is. Learn to delegate the boring work and keep the judgment calls human.
