Moravec’s Paradox: What It Means for Engineers, AI, and Our Kids Artificial intelligence keeps surprising us. It writes code, trades stocks, beats world champions at chess — yet struggles with things a toddler does effortlessly: recognizing context, moving in the physical world, or understanding common sense. This contradiction has a name. What is Moravec’s Paradox? Moravec’s Paradox states: Tasks that are easy for humans are hard for computers, and tasks that are hard for humans are often easy for computers. In simple terms: Computers excel at logic, calculations, and formal rules Humans excel at perception, intuition, movement, and social understanding This feels backwards — and that’s why it’s called a paradox. Why is it called “Moravec’s” Paradox? The concept was articulated in the 1980s by Hans Moravec , a robotics researcher at Carnegie Mellon University. At the time, most AI researchers believed that: Once we solve high-level reasoning (chess, math, logic), everything else will...

While the stock market often focuses on high-flying tech or mega-cap growth stocks, two healthcare powerhouses are quietly innovating with AI while offering stability in uncertain times : UnitedHealth Group ( UNH ) and Elevance Health ( ELV ) . Both stocks have been beaten down recently, but their AI-driven operations and diversified healthcare services make them resilient in a potential recession — and they might be worth a closer look. UnitedHealth Group (UNH) — The AI-Enabled Insurance Leader UnitedHealth Group is more than just a health insurer. Its Optum division is a massive engine of growth, leveraging AI, data analytics, and digital health technology across: Optum Health : Clinics, urgent care, telehealth, and value-based care programs.

🏗️ AI Hardware Supply Chain Explained — Like Building a Skyscraper AI is everywhere , but few people understand how the powerful machines behind it are actually built. Who makes the chips? Who builds the servers? Who runs the AI infrastructure? To make it simple, let’s imagine the AI hardware industry as a giant skyscraper project — from architects to construction crews , all the way to property managers who operate the final building. 📌 Check out this visual infographic 👇 🧠 0 & 1. Architects — Who Designs the Brains? Some companies design their own chips for internal use, while others design chips to sell. 🧠 Nvidia , AMD , Intel : Design chips for AI (GPUs, CPUs) and sell them. 🧠 Google , Apple , Tesla : Design their own chips for in-house products (like TPUs or car chips). These "architects" send their designs to companies that can actually build the silicon. 🏗️ 2. Construction Crew — Who Manufactures the ...
