No, AI coding assistants cannot take the place of human developers. They are tools that help improve work and results. Humans are still needed for design and solving hard problems. AI handles simple tasks so we can focus on the harder parts. The best way is for humans and AI tools to work together.

The safety of these tools depends on each one. Some let you run them on your own system for secure use. Business versions often include strong safety tools. Always read the tool's privacy rules before using it with private code. Tools like Tabnine and CodeGeeX let you run them locally to keep your code safe. Always check the safety options before using them for private work.

Reports show that AI coding assistants can boost productivity by 30–50% for simple tasks. Developers say they spend less time on comments and basic code. How much they help depends on the tool and how you work. Most people save a few hours each week after getting used to the tool. As the tool learns how you code, it becomes more helpful.

Codeium gives great value with its free plan for solo developers. GitHub Copilot has strong features for $10 per month. For teams, Tabnine’s $12 per user plan has many business tools. The best value depends on how you plan to use the tool. Many tools let you try them for free, so test them before paying.
