Artificial intelligence (AI) has been defined as the theory and development of computer systems able to perform tasks normally requiring human intelligence, such as visual perception, speech recognition, decision-making, and translation between languages.

It is evolving rapidly.

ChatGPT-4, the latest enhanced iteration of the popular AI app, was recently released. GPT stands for ‘generative pre-trained transformer’, a program that can write like a human.

A recent article in The Economist describes ChatGPT as “an AI conversationalist” that has “dazzled users with its passable impression of a human interlocutor … conjuring up … human-like texts, images and sounds by analysing reams of data on the Internet”.
