Computers used to be huge, taking up an entire room, yet modern smartphones that fit in your pocket are millions of times more powerful than those room‑sized mainframes. So how did we get from heavy, slow computers to incredibly powerful smartphones? Well, in this video, we’ll explore the evolution of computers over the past 80 years and also look ahead to the future of computing and AI processors. Throughout the video, we’ll focus not just on transistor counts and Moore’s law, but on the fundamental technological shifts between generations of computers.  So stick around and let's explore the Evolution of Computers!

A comprehensive historical overview tracing computer evolution from 1945-1977, covering the transition from vacuum tube mainframes to transistorized systems and early integrated circuits. The content explains how computers progressed from room-sized machines like ENIAC to personal computers, detailing the technological shifts from vacuum tubes to transistors to packaged ICs. It examines IBM's mainframe dominance with the System 360, the development of CPUs like the Intel 4004 and MOS 6502, and why market leaders failed to adapt between technological ages. The video uses 3D models of 60+ devices and Lego brick analogies to visualize computational power increases.
