Stop Thinking Machine Learning Is Magic — Here's What It Actually Does

Dear younger me (or whoever's reading this from Kalyan), Last month, I was on the 7:42 AM local from Kalyan Junction to Dadar — you know, the one that's always packed by Dombivli — and I overheard two guys talking. One of them said, "Bro, machine learning will replace all of us. It's AI. It's finished." The other guy nodded like he…

I was wrong about ChatGPT . Six months ago, when the hype first hit, I did what most analysts do—I panicked quietly and told myself I'd figure it out later.
