27 years ago, The Pragmatic Programmer taught us, "it's all text, learn your tools, and learn a new programming language every year."
It's 2026. It's all still true, but for a few details. It's all text. Learn your tools. And learn a new LLM every year.
I don't mean toy with it or hop around. I mean learn it. Pick one and stick with it. Use Claude until you understand how it feels more creative and present to the human in the room. Use Grok until you can predict when dry wit and an allergy to bullshit will reign. Dive into Gemini until that deep research librarian mode feels natural. Copilot and Perplexity and DeepSeek have flavors, too. Pick one and learn it.
ChatGPT, too, I guess. I don't talk about my exes.
