Tech that just got out.Explained so a 12-year-old gets it, checked against the original paper, then turned into business ideas you can test this week.
Format
Evergreen “What is X” pages for a 12-year-old.
Explainer/Artificial intelligence
A large language model writes by guessing the next piece of text, over and over. Here is how it is built, what it is genuinely good at, where it fails, and how to get better answers out of it.
A humanoid robot copies the human body so it can use buildings and tools made for people. Learn how it balances, how it learns, and how to read a demo video.
Explainer/Drones & autonomous vehicles/Ghana · Kenya · Nigeria · Rwanda
A drone is an aircraft with nobody on board. This guide explains how one stays in the air, the main types, the jobs drones do well, and the rules you have to follow before you fly.
Explainer/Digital twins & Industry 4.0
A digital twin is a live computer copy of a real machine or building, fed by its own sensors. Learn the three parts every twin needs and how to spot one that is only a shadow.
A data centre is the building your apps actually live in. Here is what fills the racks, why power and cooling can never pause, and how to judge whether a site is any good.
A cobot is a robot arm built to work beside people, not behind a fence. Learn what makes one safe, what it is good at, and the checks to make before buying.
Explainer/Semiconductors & chips
A chip fab is the factory that prints computer chips onto slices of silicon. Here is how one works, why it costs billions, and why only a few places can build the most advanced kind.
Explainer/Brain-computer interfaces
A brain-computer interface turns brain activity into commands for a machine. This page explains the three ways to pick up the signal, what these devices do well, and why they cannot read your thoughts.
6G is the next rulebook for mobile networks, and it is still being written. Here is what it is meant to do, when the first networks are due, and why your phone cannot be upgraded to it.
5G is the fifth generation of mobile networks, built for more data, faster replies and far more devices. Learn how its three radio bands differ and why your 5G may feel slow.
Cloud computing sends your data to the computer. Edge computing sends the computer to your data. Learn the four differences that decide which one a job needs.
AR adds to the real world, VR replaces it, and MR blends the two so digital objects obey your furniture. Here is how to tell them apart in one minute.
