Chaddha: AI and vibe coding will create 3 billion programmers
“Using AI, I think everybody, eight billion people in the world will be programmers because they'll vibe code. That's why this is a hundred X opportunity. It's really a hundred X because hundred X times thirty million is three billion. So there will be three bi…”

Chaddha: Only hardware, model labs, and coding agents reach $100M quickly
“I think the third area where the revenue ramp is happening is coding agents, which is cursor and lovable. I can tell you everything else is slow, which is to get to zero to a hundred, it ain't happening in one year. So it's hardware. Models, and these coding o…”
