Frequently Asked Questions

Is AI making developers redundant?

No. AI coding tools are making developers more productive — not replacing them. The tasks that remain (system design, stakeholder communication, security, complex problem-solving, code review) still require human expertise. Junior developers using AI can produce senior-level outputs; senior developers become 10x engineers.

What is the best free AI coding tool in 2026?

Cursor's free tier (2,000 completions) is excellent. GitHub Copilot is free for verified students and open-source maintainers. Claude's free tier handles complex coding questions. Bolt.new has a useful free tier for prototyping.
