I started heavy usage in April 2025 (Codex CLI -> some Claude Code and trying other CLIs + a bit of Cursor -> Warp.dev -> Claude Code) and I’m still learning as well (and constantly trying to get more efficient)

(I had been using GitHub Copilot for 5+ years already, started as an early beta tested, but I don’t really consider that the same)

I like to say it’s like learning a programming language. it takes time, but you start pattern matching and knowing what works. it took me multiple attempts and a good amount of time to learn Rust, learning effective use of these tools is similar

I’ve also learned a ton across domains I otherwise wouldn’t have touched
