Basics of AI & Agents

I started vibe coding using Lovable back in October 2025, and learned more about AI-Assisted Programming in November 2025. I switched to VS Code with the Codex extension, then moved to Antigravity with Gemini, then finally settled on Claude Code CLI. From web to IDE to CLI, it was a rather quick transition. Without a CS degree, it was a bit difficult to learn these topics, so I grinded through a shit ton of resources — 500+ hours of AI projects and studying, millions of tokens, and a lot of effort — to make a comprehensive textbook so you don't have to waste time finding resources.

Thinking back now, I've always been a lover of technology. When I was young, I used to (and still do) love playing sandbox games where I could build things from scratch. In high school, I fell in love with the only 3D printer we had and spent 4 years on it, printing some cool stuff. Now, it's the AI era. The fact that you can build an application, web app, and more with the assistance of AI so easily and quickly truly unlocks so much potential for so many people. This is just like a new industrial revolution. This is the perfect time to learn these new AI-related skills and apply them to your work and life. Embrace or extinguish — that's my mindset. And of course, I've decided to fully embrace this wave of AI.
