As a leading researcher in the field of artificial intelligence and neuroscience, Rachel had been studying the human brain's neural patterns and their relation to advanced machine learning algorithms. She had a hunch that this file might be connected to her work. The hard drive ejected itself from Rachel's computer,

The woman, who appeared to be in her mid-30s, started speaking in a calm, measured tone. "Hello, I'm... test subject 515. I've been part of a... program, designed to enhance human cognition and merge it with machine learning capabilities."
