Notable Positions

On Learning to Program with AI

In his State of AI 2026 episode, Fridman describes using Claude Code to "build the skill of programming with English" — a fundamentally different experience from traditional coding where you guide the model at a macro level rather than micromanaging code details.

On Model Loyalty

Describes the "threshold effect" of model switching: users fall in love with a model after one impressive result, then abandon it after one failure, creating constant churn between ChatGPT, Claude, and Gemini.

Key Quotes

• "The experience is fundamentally different. You're thinking in this design space and just guiding it at this macro level, which is another way of thinking about the programming process." (on Claude Code)
• "Some smart thing and then you fall in love with it, and then it does some dumb thing and you're like, I'm going to switch." (on model switching behavior)
