Reviewers largely see GitHub Copilot as a strong, always-on coding aid that fits naturally inside the IDE, speeds up boilerplate, autocomplete, and repetitive work, and helps developers stay in flow, learn patterns, and switch languages or frameworks more easily. Several say it has improved a lot, with better context awareness and some larger-codebase support. The main caveat is reliability: suggestions can be generic, buggy, or confidently wrong, so users still expect to refine, review, and guide it rather than trust it on bigger or project-specific tasks.
