Product: Sapient & sentient artificial intelligence
Customer: any applicable market can adapt it to suit to their needs. For example, students can have a tutor/mentor. At the same time, doctors in a hospital can speak to it to help with diagnostics/reasoning. Even further, can be applied to maintain electrical infrastructure - if users are at home, it can automatically adjust lights/temperature, etc, per room; if no one is, can adjust to save money.
