The AI models behind Copilot, Claude, ChatGPT, and Cursor do not run on your laptop. They run on massive GPU clusters in data centers that could be a thousand miles from your desk. Every prompt you send takes a physical journey through internet infrastructure to reach those servers, and every response makes the trip back.
That journey is measured in milliseconds, and milliseconds add up. If your connection has 80 ms of latency to the nearest data center, every single suggestion in your AI coding workflow is at least 160 ms slower than it needs to be. Multiply that by hundreds of suggestions per day, and you are losing meaningful chunks of focus time to the network alone.
This is where fiber or a top-tier cable plan wins over slower alternatives like DSL or satellite. Fiber has fundamentally lower latency because light in glass moves faster than electrons in copper, and because fiber providers usually have better routing to major cloud data centers. If you want a deeper look at why AI tools reward fast connections so much, this Excitel breakdown of how fast internet powers AI tools is a good primer.
