What is the video all about? Choose two statements that refer to the main ideas of the video.

1. AI has been around since the 1940s and is widely used in everyday technology.

2. AI is increasingly used in autonomous vehicles for navigation and decision-making.

3. AI algorithms play a significant role in financial markets, where they are used for high-frequency trading and predictive analysis.

4. AI can't think or feel; it only mimics human responses without understanding or emotions.

#1. AI is as old as your (1) . So, the first thing to know is that AI has been around a lot longer than you might think. Its roots lie in an idea known as an "artificial neural network" from the (2) . A neural network is a bit like a team of (3) that learn to solve problems. Each time they come up with a possible solution, it's marked. If there is room for improvement, they adjust and change their connections. Over time the network becomes more (4) . And technology powered by neural networks is all around us right now. It suggests movies and music we might like. It (5) and objects when taking photos on smartphones, enabling features like (6) recognition. It's heavily used by social media platforms to personalize our (7) . More recently, a form of AI known as "generative AI" is powering applications that can seemingly create new data. It can also power (8) like Open AI's ChatGPT and Google's Bard, which give humanlike responses to questions. These are getting better at interacting with us, and seemingly more humanlike. This can seem scary, but it's worth knowing point two.

#2. AI can't feel or think. If you ask ChatGPT a question like this one - "Why should we be concerned about AI?" - it does a pretty good job of providing a response that appears (9) . And with that convincing humanlike response, it's easy for us to believe it understands what it's saying, that it has feelings and (10) . It's understandable that we do this, but it's worth remembering, right now AI can't think or feel, can't (11) . ChatGPT and its (12) are sophisticated sentence completion apps that analyze our patterns of communication and provide responses similar to the way humans would typically reply. A bit like a (13) . Which leads us to point number three.

#3. AI makes stuff up. Chatbots can have an (1) with the truth, technically known as "AI (2) ". You could also describe it as "making stuff up". The (3) of the technology is a model that uses probability to (4) the next word, sentence or paragraph. It can generate seemingly (5) replies, but lacks the ability to assess truthfulness or the accuracy of its responses. So anyone thinking of using chatbots to write content needs to be careful they're not incorporating credible-sounding BS that can be easily (6) someone who's actually done the research.

#4. AI can sound racist and sexist. The idea of a racist machine might seem (7) -. But if AI is trained on data that's racist, biased or hateful, then its output will be too. As we all know, racism, bias and (8) can be found in abundance online. In 2016, Microsoft launched an experimental chatbot called Tay, but quickly (9) after it made racist and (10) remarks. It learnt to do this from interacting with users on social media. Microsoft apologized and promised to implement improved safety features in future. This is why the ethical framework that governs any AI application is incredibly important, and why many are calling for (11) to prevent bias and hate speech to be built into AI systems.

#5. AI has incredible potential. For all the notes of caution, it can be easy to forget there's many potential benefits to AI. It's set to truly revolutionize healthcare. AI has already discovered new drugs and is being used to identify cancer cells much more reliably than humans. And AI chatbots can behave like patient teachers when we struggle to understand a complex topic, summarising huge volumes of information for us. The AI revolution has the potential to enhance and (12) work in many fields, from software programming, to (13) , to law enforcement and journalism. This has pluses and minuses, of course, but could this extra capacity free us up to do other things? Like (14) climate change or looking after ourselves and each other better? As AI advances, governments and regulators will of course need to make sure it's being used (15) and legally - no easy feat. But will AI take over the world? Don't forget, AI is a tool, and even a powerful tool can't take over the world on its own. It's up to us to decide how we use it - or even if we should use it at all.
