Intelligence is the cognitive ability to understand the world; to help achieve a wide variety of goals; and to integrate and adapt such knowledge and skills in ongoing learning. It needs to function in real time, in the real world, and with limited knowledge and time.
Human intelligence is special in that it features the ability to form and use highly abstract concepts, and to think and reason using symbols (language).
Here’s a list of distinctive and essential features of human intelligence, and thus advanced AI (also see AGI Checklist):
It must be general: An individual intelligence must be able to learn and do a wide range of cognitive tasks
Real-time interactive learning utilizing environmental feedback
Learning, reasoning, and acting under knowledge and resource constraints
Unsupervised and self-supervised learning. One-shot/ instance learning
Short and long-term memory of interactions, plus prediction
Selective unlearning and re-learning (i.e. correcting errors)
Learning, recognition, and reasoning utilizing dynamic context and goals
Real-time autonomous concept formation, including highly abstract ones
Natural language ability, including deep understanding
Real-time adaptive focus and selection
Has concept ontology grounded in experience, including cause and affect relationships
Inherent transfer-learning: knowledge and cognitive skills can be applied to any domain
Deep integration and synergistic interaction of knowledge, memory, cognition and skills
Introspection, and meta-cognitive control
Cognition/ reasoning that includes a theory-of-mind (other agent’s mental states)
Artificial intelligence has these additional desirable characteristics:
Data and algorithms are scrutable (not black box)
Externally generated ontologies and skills can be integrated
External conventional databases and programs can be deeply connected
‘Brains’ can be merged
Interestingly, the current focus in AI research is on machine learning, which address few of these requirements of intelligence.
So one may ask, why are so few people working on ‘real AI’ — why don’t we have AGI yet?

Symbols are not unique to humans. The great apes can learn to communicate with symbols. Other animals may use something similar. What is unique about humans is language. Language uses symbols, but it also uses grammar. Without grammar we can not communicate effectively. Try it.
