Comment CABLE and I’ll send you the full breakdown of how AI infrastructure actually works. 👇 Your prompt crosses an ocean and comes back before you finish blinking. 🌊 Here’s what physically happens when you hit send. Your words become zeros and ones, then get chopped into tiny packets. They leave your device, hit your router, run down fiber to your ISP’s regional hub, and shoot toward the data center. And if that data center is on another continent? Your prompt turns into pulses of infrared light, fired through cables lying on the ocean floor. 💡 Light moves through glass at roughly 125,000 miles per second — so thousands of miles takes about 40 to 80 milliseconds. Then it lands. Routed to a specific rack packed with GPUs and TPUs, reassembled, fed to the model. Then it lands. Routed to a specific rack packed with GPUs and TPUs, reassembled, fed to the model. Here’s the interesting part: you never sit staring at a blank screen. The GPU produces the answer bit by bit, and the server ships each chunk out the moment it exists. That’s why the words appear as they’re being written. ⚡ Your data is flying across the planet and back, faster than you can read this sentence. - @build.with.alan
