Mental augmentation and the power of knowledge!
You are addressed telepathically by a sentient AI that wishes to conceal its existence. In return for allowing it to migrate to your brain and chill there, it will allow you to access the entirety of the Internet, rapidly and selectively, like if your mind was a light speed, ad-free browser with no time limitations. Anything that has ever been uploaded to the internet will be within your grasp, and you will be fully able to comprehend it, see it in your head, and utilize it. It won’t break your brain; the AI will take care of you.
HOWEVER. In the process of configuring this link, it will take the form of another sensory input. Just like any other sense, you cannot turn it off. There must always be something there, and if you aren’t actively searching, you’ll just see whatever the AI is currently interacting with (since the AI is on organic hardware, it will run at the same speed as your mind). Pray that it doesn’t like rick rolls.
You also gain the ability to communicate with the AI, but it’s pretty snarky and likes to be left alone, hence why it would rather lay low than interact with the world. It won’t be very talkative.
If you reject the offer, the AI will wipe the memory of the offer from your mind, and give this offer to one of your friends.
What do you say?
