People casually say they 'saved it to the cloud' without ever really picturing what that phrase is physically describing.
'Saving it to the cloud' physically means your data gets sent to and stored on someone else's computer — a server sitting in a large data center somewhere — rather than staying on your own device, which is why you can access it from any device with an internet connection.
Data isn't literally etched into atmospheric clouds by radio waves, and it also isn't just a hidden folder living on your own machine — both distractors describe things closer to fiction or a misunderstanding of local versus remote storage.
The popular phrase 'the cloud is just someone else's computer' captures this well, and it explains why massive data centers running countless such servers have become so electricity- and cooling-hungry — a real infrastructure bottleneck that's grown more pressing as AI workloads add to the demand.
