AI coding tools are no longer just autocomplete engines.
For the last few years, developers used AI mainly to write faster: generate a function, explain an error, complete boilerplate, or suggest a code snippet. That was useful, but the human developer still controlled almost every step.
Now the shift is toward agentic software development.
Tools like OpenAI Codex and Google Antigravity are not only helping developers write code. They are starting to inspect repositories, understand tasks, edit files, run commands, verify outputs, and return work for human review.
But Codex and Antigravity are not the same kind of product.
