You go back in time 10 years and you're the only one with access to ChatGPT. How do you make the most money?

A hypothetical scenario has gone viral on Reddit, posing a unique challenge for tech enthusiasts: you are transported back to 2016 as the sole person on Earth with access to a powerful AI. The model, described as being as capable as a hypothetical 'GPT-5.4,' is a game-changing asset, but comes with critical constraints. Its training data cuts off at the end of 2015, meaning it cannot provide specific information about future events like election results or stock prices. Most crucially, the AI's existence must remain an absolute secret; if anyone discovers you have it, it disappears entirely. This creates a fascinating puzzle about covertly leveraging a world-altering technology.

The discussion has sparked thousands of comments debating optimal strategies for wealth generation. Popular ideas include using the AI's superior reasoning and coding capabilities to anonymously develop and sell revolutionary software, create groundbreaking scientific research papers, or write bestselling novels and screenplays under pseudonyms. Others suggest more indirect paths, like using the AI to become an impossibly successful day trader or sports bettor by analyzing pre-2016 data with superhuman skill, carefully masking the source of the advantage. The thought experiment highlights the immense, disruptive value of advanced AI as a pure intelligence multiplier, separate from its knowledge of future events.

The scenario forces a focus on the AI's core competencies—analysis, creativity, and problem-solving with existing information—rather than simple clairvoyance. It underscores how a sophisticated LLM could accelerate innovation and creation in any field, acting as the ultimate silent partner. The viral response reflects a broader cultural fascination with AI's potential and the ethical, strategic dilemmas that come with possessing asymmetric technological power long before the rest of the world catches up.
