Abstract ===== Artificial Intelligence (AI) has, for decades, been mired by one important and immutable fact; we have no description, definition, quantification or measure of intelligence. But not understanding something doesn’t mean to say we cannot use and exploit it! This has led to some discrediting of AI, which is often seen as not delivering on its early promise! Such a view is short sighted and missing the essential point that machine-based intelligence now supports the human race and all human life to an extensive degree. I think we can safely assume that if we were to switch off all the operational AI systems on the planet, our very civilization would be at great risk, and in some significant manner, it would fail! In this presentation we examine intelligence from both a silicon (designed) and carbon (evolved) point of view, and move on to our relationship and reaction to systems that are both abstract and anthropomorphic. We then address a most fundamental question; what makes something intelligent? Using a series of logical delimiters we move on to develop a measure of intelligence fundamentally based on a process originally developed by Frank Drake @ NASA to estimate the number of civilizations in our galaxy. We then hypothesise the final form of a complete descriptor for a generalized intelligence.
