Artificial intelligence
The science of creating machines with the ability to develop problem-solving and analysis strategies without significant human direction or intervention.
The Explain card
- Plain English
- Artificial intelligence is the broad field of building machines that can work out how to solve problems and analyse situations without a human spelling out every step.
- Example
- A fraud detection system at a bank learns what normal card activity looks like and flags a midnight purchase in another country, with no analyst writing a rule for that exact case.
- Why it matters
- Once software decides things on its own, attackers stop targeting only the code and start targeting the reasoning: the data it learned from, the inputs it sees, and the outputs people trust.
- Hook
- AI is software that figures out the "how" itself, so you must defend the thinking, not just the code.
Word knowledge
How the word is built, where it came from, and what it sits beside in memory.
In a sentence
On the mail gateway, artificial intelligence scores each inbound message for phishing before an analyst opens the queue.
Why these words
- artificial Latin artificialis, of or belonging to art marks the named faculty as made by craft rather than found in nature
- intelligence Latin intelligentia, understanding, from intelligere, to pick out supplies the head noun, the faculty the phrase ascribes to a machine
Where it came from
- Origin
- English coinage by John McCarthy, from Latin artificialis (of art) and intelligentia (understanding)
- Entered the language
- 1955
- What changed
- Artificial had meant made by craft since the late 1300s, and later also fake. Intelligence had meant understanding, then news, then secret information. McCarthy joined the two words in 1955 to name a research program, and the phrase became the ordinary label for systems that act as if they think.
