Opus 4.5 is going to change everything

Claude Opus 4.5 has fundamentally changed one developer's perspective on AI replacing programmers, enabling him to build four complete applications in hours rather than months. The AI successfully created complex projects including a Windows image converter, video editing software, and full-stack mobile apps with Firebase backends, handling everything from authentication to deployment automatically. Unlike previous AI coding tools that produced buggy code, Opus 4.5 debugs its own errors and writes production-ready applications, leading the author to conclude that AI can now genuinely replace developers for many tasks.
