The idea is to equip users with an AI that helps people make decisions, especially those numerous decisions that we have to make every day. It would help the user make decisions that the user cannot make optimally and will be recommended for decisions that are not so important but can be time consuming.
With the advances in technology and the constantly rising standards of living. There are so many options to choose from when you want to choose the clothes you wear, the food you eat, or even which piece of furniture to buy.
For example, when one is at a new restaurant they would usually want to read through the whole menu before deciding what to eat. The list of the optimal options could be made by the AI for every restaurant you could visit for the whole day while considering the nutritional requirements, allergies, and likely moods even before you wake up.
Letting the AI decide such little things for users will make them live more productive lives by freeing up more time for the more important things. It would also make the user more conscious of their decision making processes. It will reduce the chances of the user making impulsive decisions that have no logical backing.
For this to work, the AI will have to be with the user at all times or most of the time. It would be ideal to incorporate the AI with something like google glasses. The input devices will record what the user sees and does. It would also be calibrated to observe the user's brain activity that so it can detect when the user is pondering over something. The AI will have the ability to initiate the conversations like a voice assistant and use more discreet means of communication like sending its user an email.
A major challenge with such a system is that whoever provides such a service will have access to the the users' private information and any leakages could be disastrous. They can also be used to control people's behaviors to an extent; since it is only natural to trust the logical decisions of a computer.
