Eighty years of inventions and what they tell us about AI.

Every tool that now feels ordinary was once new, a little odd, and hard to trust. Artificial intelligence (AI) is at that stage now. Looking at how earlier inventions arrived can help you decide how much to rely on an AI assistant such as ChatGPT, Gemini, Claude or Copilot, and what to check before you do.

A room-sized calculator

On 14 February 1946 the University of Pennsylvania announced ENIAC, the Electronic Numerical Integrator and Computer. It weighed about 27 tonnes and filled a room of roughly 9 by 15 metres (University of Pennsylvania School of Engineering and Applied Science; Penn Today). Only specialists could use it. Nobody then pictured one in a pocket.

The question and the name

In October 1950 the mathematician Alan Turing published "Computing Machinery and Intelligence" in the journal Mind, which opens with the question "Can machines think?" (Mind, volume LIX, number 236, pages 433 to 460). On 31 August 1955 four researchers, John McCarthy, Marvin Minsky, Nathaniel Rochester and Claude Shannon, wrote a proposal for a summer research project at Dartmouth College. It is the earliest document to use the term "artificial intelligence", and it led to the 1956 summer project (AI Magazine, Association for the Advancement of Artificial Intelligence, 2006 reprint).

Inventions that arrived in ordinary life

• Television. In 1950 fewer than one American home in ten had one. By 1960 almost nine in ten did (United States Census Bureau, September 2023).
• The cash machine. The first one was unveiled on 27 June 1967 at a Barclays Bank branch in Enfield, north London (Barclays Group Archives).
• The mobile phone. The first handheld call was made on 3 April 1973 in New York by Martin Cooper of Motorola. The prototype weighed about a kilogram (Vodafone UK; NPR; CBS News).
• The personal computer. IBM introduced its Personal Computer on 12 August 1981 (Computer History Museum).
• The text message. The first one, "Merry Christmas", was sent on 3 December 1992 (HISTORY).
• The web. On 30 April 1993 the European Organization for Nuclear Research (CERN) put the World Wide Web software in the public domain, so anyone could use it freely (CERN).
• The smartphone. Apple announced the iPhone on 9 January 2007 and it went on sale on 29 June 2007 (Apple Newsroom).
• The chatbot. OpenAI released ChatGPT on 30 November 2022 (OpenAI).

What AI is, in plain words

The Organisation for Economic Co-operation and Development describes an AI system as a machine-based system that, from the input it receives, works out how to produce outputs such as predictions, content, recommendations or decisions. The United Kingdom government's Generative AI Framework puts it more plainly: a broad field that aims to use computers to emulate the products of human intelligence (Central Digital and Data Office, January 2024).

You already use a small version of this. When your phone suggests the next word as you type, it is predicting what is likely to come next. Apple says its suggestions draw on your past conversations and writing style (Apple Support). Google says Gboard uses language models for next-word prediction (Google Research, 19 April 2024). Large language models, the technology behind chatbots, work on a similar idea at a much larger scale. The United Kingdom government framework says they predict the next word in a sequence and do not understand the meaning of the words beyond how likely they are to be used together.

How to use one well

Because a chatbot is built to produce likely, fluent sentences, it can sound sure when it is wrong. The United Kingdom government framework warns of content that appears plausible but may be factually incorrect. OpenAI's own launch post says ChatGPT sometimes writes plausible-sounding but incorrect or nonsensical answers (OpenAI, 30 November 2022). The word for this is "hallucination", and the New Zealand government's guidance notes that the Organisation for Economic Co-operation and Development defines it as incorrect yet convincing output.

Each earlier invention came with its own habits. People learned to cover a cash machine keypad, to be wary of unexpected texts, and to look for the padlock in a web address. AI has its own habits to learn:

1. Check anything that matters. For health, money, law or safety, confirm the answer with an official source or a professional.
2. Keep private details out. Leave out passwords, account numbers, identity documents and other people's personal details. UtilForge.org's free Hide Names From AI tool helps you remove names before you paste text. It runs on your own phone or computer.
3. Treat requests for money the same as ever. An AI-written message can be fluent and still be a scam. If a message asks for payment, use the free Before You Pay check.
4. Ask where the answer came from. If the assistant cannot point to a source you can open, treat the answer as a lead to check, not a fact.
