Before ChatGPT became a household name, Microsoft and OpenAI were already betting big on AI for developers. In spring 2021, they launched GitHub Copilot, a tool that watched you code and tried to autocomplete your work in real time.
That was just the beginning. What started as an experimental autocomplete feature has turned into a full-blown category war, with every major tech company racing to build the best AI coding assistant.
The timing makes sense. Writing code was always going to be one of AI's strongest use cases because it's structured, testable, and has clear right and wrong answers. Plus, developers were already comfortable with autocomplete and tooling that augmented their work.
For anyone building products or working with development teams, this matters more than you might think. AI coding tools are quickly becoming as essential as IDEs themselves, changing how fast teams can ship and what's possible for non-technical founders.
The competition is heating up fast. What was once just Copilot now includes tools from Anthropic, Google, startups, and open source projects. Each is trying to prove they can help developers write better code faster.
The real question isn't whether AI will change how we code anymore. It's which tools will win, and how much of the traditional development workflow gets reimagined in the process.
