Intelligence refers to learning speed, retention percentage, and a measurement of the ability to apply information to whatever situation is put before you. The ability to use ones senses completely in order to aquire data. The ability to recognize patterns found in the data. The ability to extract instructions from data in order to learn behaviors. The ability to correctly extend patterns indefinitely or to a logical end.
The pinnacle of intelligence is to learn without repetition and to apply all knowledge simultaneously to every challenge and succeed the first time. It is the ability to apply learned behaviors to situations and to create similar behaviors in order to succeed in similar situations.
Intelligence is not the ability to feel. It is not the desire to exist. It is not a drive to succeed. It is not a fear of death. No order of magnitude of intelligence is a sign of life. Intelligence itself is simply a mechanism for adaptation and success.
Animals, including humans, have special genetic knowledge and stored behaviors. We are programmed to feel hurt when our pain receptors fire signals to our brains, and to respond in some appropriate way. This programming is no different than a biological analog of a computer program. Some people claim that this makes computers unintelligent, that because they have to be programmed by people, they have no intelligence of their own. This argument is a good way to identify people who know nothing about intelligence or biology.
Computers are inherently intelligent. They are capable of using every sense attached to them to store and retain 100% of all incoming data. Programs can then be used to recognize patterns in all stored data. This in itself gives computers the potential to be as intelligent as their hardware limitations allow.
Many IQ tests have an expectation of a quantity of knowledge and a capacity to solve problems that scales with age. They are usually adjusted for the times we live in. These tests are not a good choice for objectively determining intelligence.
