In this final lesson, I take a moment to reflect on the journey we've taken together through building CLI applications in Go. What started as a three-month project evolved into six months of comprehensive content creation, resulting in one of the most thorough courses on CLI development available. I express my gratitude to everyone who purchased the course and congratulations to those who made it through the extensive material. It's been quite a journey for both of us. I also share my evolving perspective on AI and software development. While initially skeptical, the emergence of terminal-based AI tools like Claude Code and ChatGPT Codex around March/April 2025 changed my view on the future of coding. Ironically, as AI transforms how we write code, the skills for building excellent CLI applications become even more crucial. The terminal remains at the heart of modern development workflows, making the knowledge gained in this course more relevant than ever. Thank you for joining me on this journey, and I hope the skills you've learned serve you well in this evolving landscape of software development.
