I asked Claude to build an operating system from scratch. A few days later it was running on a real laptop

A user challenged Claude to build a DOS-like operating system from scratch that could boot from a USB on real hardware. The project, named "ember," was successfully developed and is now running on an old Lenovo Yoga laptop. The user documented the process and shared the code on GitHub, demonstrating Claude's capability in creating functional software from initial concept to deployment on physical hardware.

This report uniquely details Claude's capability to build a functional operating system from scratch and run it on real hardware, unlike typical AI code generation examples.
