I know nothing about Go, but if it's like other platforms, builds intended for production or staging environments are indeed nearly always for x86_64, but those are done somewhere besides laptops, as part of the CI process. The builds done on the laptops are to run each developer's local instance of their server-side application and its front-end components, That instance is always being updated to whatever is in-progress at the time. Then they check that code in, and eventually it gets built for prod on an Intel, Linux system elsewhere.
