Three case files on what's actually possible with AI right now — who's building it, what it's earning them, and why nobody is too young, too old, or too far behind to start. Every number below is sourced, not hypothetical.
One person, one laptop, and an AI stack that used to require a five-to-ten person team. These four never raised venture money.

Zero to app in 2 hoursInside companies, the gap isn't between people who use AI and people who don't anymore — it's between people who direct agents and people who still do the work by hand.
