Because the computer only simulates having a mind of its own.

While computers can realistically simulate the metal covering of T-1000, they still cannot produce realistic human skin, let alone facial expression.

Science teachers, for example, could use computers to simulate experiments that would be too expensive or dangerous to conduct in a school laboratory.

More exciting, he said, is the way computers can simulate a building's performance under various conditions.

In the same way, he says, computers can simulate the processes of a conscious brain, but that does not mean it is conscious.

Ultimately the computers could simulate what could not be seen.

In this approach, known as genetic algorithms, a computer simulates the performance of a group of machines, each with a slightly different design.
