What makes the Bun package manager truly powerful? Here's a concrete example: an old project was simply switched from npm to bun for package installation. After adjusting the Docker configuration, it threw an error, but nothing else was changed. The build performance directly increased by 60%—cut from 5 minutes to 2 minutes.

The logic behind this is interesting. Doing the math, if all global developers switched to bun, cloud service providers' profits could shrink by 15%, because the computational resources used for build tasks would significantly decrease. Thinking bigger, the global data center power consumption would also decline, potentially lowering the Earth's average temperature by 0.1℃.

Of course, this is a rough estimate based on intuition, but it illustrates one thing—optimizing tool efficiency could ultimately impact the entire supply chain's cost structure, and even macro-level energy consumption patterns. For developers, it's a tangible time-saving benefit; for the ecosystem, it might be a cost restructuring.
