What is AI?

While a number of definitions of artificial intelligence (AI) have surfaced over the last few
decades, John McCarthy offers the following definition in this 2004 paper,
" It is the science and engineering of making intelligent machines, especially
intelligent computer programs. It is related to the similar task of using computers to understand
human intelligence, but AI does not have to confine itself to methods that are biologically

However, decades before this definition, the birth of the artificial intelligence conversation was
denoted by Alan Turing's seminal work, "Computing Machinery and Intelligence",
which was published in 1950. In this paper, Turing, often referred to as
the "father of computer science", asks the following question, "Can machines think?" From there, he
offers a test, now famously known as the "Turing Test", where a human interrogator would try to
distinguish between a computer and human text response. While this test has undergone much scrutiny
since its publish, it remains an important part of the history of AI as well as an ongoing concept
within philosophy as it utilizes ideas around linguistics.

Stuart Russell and Peter Norvig then proceeded to publish, Artificial Intelligence: A Modern
Approach , becoming one of the leading textbooks in the study of AI. In
it, they delve into four potential goals or definitions of AI, which differentiates computer systems
on the basis of rationality and thinking vs. acting:

Human approach:

Systems that think like humans
Systems that act like humans

Ideal approach:

Systems that think rationally
Systems that act rationally

Alan Turing’s definition would have fallen under the category of “systems that act like humans.”

At its simplest form, artificial intelligence is a field, which combines computer science and robust
datasets, to enable problem-solving. It also encompasses sub-fields of machine learning and deep
learning, which are frequently mentioned in conjunction with artificial intelligence. These
disciplines are comprised of AI algorithms which seek to create expert systems which make
predictions or classifications based on input data.

Today, a lot of hype still surrounds AI development, which is expected of any new emerging
technology in the market. As noted in Gartner’s hype cycle , product
innovations like, self-driving cars and personal assistants, follow “a typical progression of
innovation, from overenthusiasm through a period of disillusionment to an eventual understanding of
the innovation’s relevance and role in a market or domain.” As Lex Fridman notes here (01:08:05)
in his MIT lecture in 2019, we are at the peak of inflated expectations,
approaching the trough of disillusionment.

As conversations emerge around the ethics of AI, we can begin to see the initial glimpses of the
trough of disillusionment. To read more on where IBM stands within the conversation around AI
ethics, read more here.
