What is an expert system?
"A computer application that performs a task that would otherwise be performed by a human expert. For example, there are expert systems that can diagnose human illnesses, make financial forecasts, and schedule routes for delivery vehicles. Some expert systems are designed to take the place of human experts, while others are designed to aid them.
Expert systems are part of a general category of computer applications known as artificial intelligence . To design an expert system, one needs a knowledge engineer, an individual who studies how human experts make decisions and translates the rules into terms that a computer can understand."

What are the problems with expert systems?
"The dependence people place on cases poses a problem to those who treat human cognition as being primarily rule-based. Much work in artificial intelligence, for example, is done in "expert systems." These systems are based on the notion that expert knowledge consists of a collection of rules. By determining the rules an expert in a domain uses, the idea goes, we may then simulate expert behavior in that domain. Not surprisingly, expert systems have run into a significant problem: they are brittle. When faced with a problem which bends the rules, they are unable to cope. They fail because they are not grounded in cases. They are unable to fall back on the details of their experience, find a similar case, and apply it."

1. Write a short paragraph for each issue addressed by this video:

1. Brain emulations is a process of "copying" a conscious mind from a brain to another storage by scanning and analyzing a real brain completely  Its also called the "mind copying or mind transfer" because it transfer the same information in the brain to a it system. 
   
   
2. Rule-based AI is a form where the human's knowledge can get achieved. Thanks of this knowledge more people would learn new things, so this means that knowledge in people may improve. Also this means that the knowledge is going to will be provided everytime someone needs it. 
3. Ethics of digital minds
4. Prospect of AI catastrophe.

2. What are the potential benefits and risks of advanced AI?

Its very interesting the advancements of the artificial intelligence but sometimes it is not positive because it can harm the human being and make them  feel not useful. The benefits can be in education, and health but also a robot can have bugs and dont do the things that he is suppossed to.
