Direct quote
The ability to navigate all interfaces available to a human doing digital work today, including the ability to process and generate text, audio, and video, the ability to autonomously control technology instruments like mice and keyboards, and the ability to access and browse the internet. The ability to interface with the physical world; controlling laboratory equipment, robotic systems, and manufacturing tools through digital connections.
