Product design question

How would you design a computer to mimic the input of brain signals from the five senses of a human being (taste, touch, smell, hear and see)?

What this question tests

Ability to handle a highly speculative, far future prompt with structured reasoning rather than pure imagination.

How to approach it

  1. Reframe the prompt as a product strategy question: what would a brain computer interface product need to solve, not literal engineering of the device.
  2. Segment potential use cases: accessibility for people with sensory impairment first, since that's the most defensible near term application, versus general augmentation later.
  3. Identify the core technical and ethical constraints: signal fidelity, safety of any invasive or non invasive interface, and informed consent given the sensitivity of neural data.
  4. Prioritize a narrow, high value first use case, for example restoring basic communication or one missing sense for people who have lost it, rather than replicating all five senses at once.
  5. Propose a phased roadmap: start with a single sense or function with clear medical need, validate safety and efficacy, then expand scope only with strong evidence.
  6. Define success as functional restoration measured against a clinical baseline, not breadth of senses covered.
