OpenAI’s artificial intelligence (AI) chatbot ChatGPT was unleashed onto an unsuspecting public exactly one year ago.

It quickly became the ever, in the hands of by the end of the second month. Today, it’s available to more than a billion people via Microsoft’s , Skype and – and OpenAI is predicted to collect more in annual revenue.

We’ve never seen a technology roll out so quickly before. It took about a decade or so before most people started using the web. But this time the plumbing was already in place.

As a result, ChatGPT’s impact has gone way beyond writing poems about Carol’s retirement in the style of Shakespeare. It has given many people a taste of our AI-powered future. Here are five ways this technology has changed the world.

1. AI safety

ChatGPT forced governments around the world to wise up to the idea that AI poses significant challenges – not just economic challenges, but also and .

United States President Joe Biden catapulted the US to the forefront of AI regulations with a that establishes new standards for AI safety and security. It looks to improve equity and civil rights, while also promoting innovation and competition, and American leadership in AI.

Soon after, the United Kingdom held the first ever intergovernmental AI Safety Summit in Bletchley Park – the place where the computer was born in World War II to crack the German Enigma code.

And more recently, the European Union has appeared to be sacrificing its early lead in regulating AI, as it struggled to adapt its AI Act with potential threats posed by frontier models such as ChatGPT.

Although Australia continues to languish towards the back of the pack in terms of regulation and investment, nations around the world are increasingly directing their money, time and attention towards addressing this issue which, five years ago, didn’t cross most people’s minds.

2. Job security

Before ChatGPT, it was perhaps car workers and other blue collar workers who most feared the arrival of robots. ChatGPT and other generative AI tools have changed this conversation.

White collar workers such as graphic designers and lawyers have now also started to worry for their jobs. One recent study of an online job marketplace found earnings for writing and editing jobs have fallen more than . might be the canary in this coalmine.

There’s huge uncertainty whether more jobs get destroyed by AI than created. But one thing is now certain: AI will in how we work.

3. Death of the essay

The education sector reacted with some hostility to ChatGPT’s arrival, with many schools and education authorities issuing immediate bans over its use. If ChatGPT can write essays, what will happen to homework?

Of course, we don’t ask people to write essays because there’s a shortage of them, or even because many jobs require this. We ask them to write essays because it demands research skills, improves communication skills, critical thinking and domain knowledge. No matter what ChatGPT offers, these skills will still be needed, even if we spend less time developing them.

And it isn’t only school children cheating with AI. Earlier this year, a US judge fined two lawyers and a law firm US$5,000 for a court filing written with ChatGPT that .

I imagine these are growing pains. Education is an area in which . Large language models such as ChatGPT can, for example, be fine-tuned into excellent Socratic tutors. And intelligent tutoring systems can be infinitely patient when generating precisely targeted revision questions.

4. Copyright chaos

This one is personal. Authors around the world were outraged to discover that many large language models such as ChatGPT were trained on hundreds of thousands of books, downloaded from the web without their consent.

The reason AI models can converse fluently about everything from AI to zoology is because they’re trained on books about everything from AI to zoology. And the books about AI include .

The irony isn’t lost on me that an AI professor’s books about AI are controversially being used to train AI. Multiple class action suits are now in play in the US to determine if this is a violation of copyright laws.

Users of ChatGPT examples where chatbots have generated entire chunks of text, verbatim, taken from copyrighted books.

5. Misinformation and disinformation

In the short term, one challenge which worries me most is the use of generative AI tools such as ChatGPT to create misinformation and disinformation.

This concern goes beyond synthetic text, to deepfake audio and videos that are indistinguishable from real ones. A bank has using AI-generated cloned voices.

Elections also now appear threatened. Deepfakes in the 2023 Slovak parliamentary election campaign. Two days prior to the election, a fake audio clip about electoral fraud that allegedly featured a well-known journalist from an independent news platform and the chairman of the Progressive Slovakia party reached thousands of social media users. Commentators have suggested such fake content could on election outcomes.

The Economist, more than four billion people will be asked to vote in various elections next year. What happens in such elections when we combine the reach of social media to with the power and persuasion of AI-generated fake content? Will it unleash a wave of misinformation and disinformation onto our already fragile democracies?

It’s hard to predict what will unfold next year. But if 2023 is anything to go by, I suggest we buckle up.
