Short version: SCOTUS upheld the rulings of the Copyright Office and lower courts that while a *prompt* can have copyright protection since it is a human work product, the output of the prompt cannot.
This is analogous to the "Monkey selfie" case where a photographer was denied copyright when a monkey took a selfie using the photographer's camera.
Why this matters: it means that if a company wants to create work product - a report, a design, a romance novel - and have that work product protected by copyright, it cannot use an AI to generate it.
It also means that any AI-generated image, report, design or book that you find, you are welcome to copy and redistribute. It is effectively in the public domain the second the AI spits it out.
