The AI timeline: how fast it's moving and what that means
In less than four years, ChatGPT has gone from novelty to necessity - from a simple writing tool to something that helps people code, design images, generate video and run detailed research with real citations.
This lesson tracks that evolution through a timeline of key milestones, from its first million users in November 2022 to nearly a billion by mid-2026. But it's not just about the tech: with each upgrade, the line between what's possible and what's practical shifts. If you still think of AI as just a writing tool, this lesson helps you update your mental model.
