When so-called "generative" Artificial Intelligences like Chat GPT and Google's Bard were made available to the public, they made headlines around the world and raised fears about how fast this type of AI was developing. But realistically, what harm could AI do to people? Is it an existential threat, or could it become one? And if things got really bad, couldn't we just switch it off or smash it up with a hammer? Technology has already completely altered our lives, and Artificial Intelligence may transform our world to an even greater degree. This series is your chance to get back to basics and really understand key technology terms. What's an algorithm? Where is "the Cloud" and what exactly is Blockchain? What's the difference between machine and deep learning in artificial intelligence, and should we all be using Bitcoin? Our experts will explain in the very simplest terms everything you need to know about the tech that underpins your day. We'll explore the rich history of how all these systems developed, and where they may be going next.

AI is now able to do some types of work faster and cheaper than human beings, and some workers have already found themselves out of a job. Earlier this year, a report from Goldman Sachs said that AI could potentially replace the equivalent of 300 million full-time jobs, and a different survey of 12 thousand people suggested that a third were worried their bosses would replace them with AI. So is AI coming for your job? What type of workers are most at risk, and if you aren't replaced, could you find yourself working alongside an AI? Technology has already completely altered our lives, and Artificial Intelligence may transform our world to an even greater degree. This series is your chance to get back to basics and really understand key technology terms. What's an algorithm? where is "the Cloud" and what exactly is Blockchain? What's the difference between machine and deep learning in artificial intelligence, and is it just jobs under threat, or is it much worse than that?

At its simplest, an algorithm is a sequence of step-by-step instructions designed to give a result. They are the building blocks of every computer program and are there to ensure every digital device gives the right results on request. For example, when we type a search query into Google, its algorithms try to give us the result we're seeking. In the case of Social Media, the algorithm's job is to keep followers on a platform, by showing engaging, interesting, and relevant posts. But over the years they’ve increasingly been entrusted with life-altering decisions, such as A-level results during the pandemic. So how are algorithms being used? Why do many people distrust them, and try to beat them? Technology has already completely altered our lives, and Artificial Intelligence may transform our world to an even greater degree.

Artificial Intelligence is already here. It's being used in products and services you already use, and is working behind the scenes in medicine, transportation, robotics, science, education, the military, surveillance, finance , agriculture, entertainment, retail, customer service, and manufacturing. How is is AI being used in these sectors, and for what purpose? And with the release of chatbots that can emulate human writing, we're now seeing websites that say they're "powered by Chat GPT". What does that mean? Technology has already completely altered our lives, and Artificial Intelligence may transform our world to an even greater degree.

Artificial Intelligence has been in the news constantly this year, from a chatbot that can write anything you can imagine, in any style, to scientists and world leaders warning that AI needs to be controlled. With the big tech firms all rushing to make their AI products available to the public, it looks like AI is likely to be part of our lives from now on. But what is it? What are the different types of AI we should know about? Are they intelligent, in a way we would recognise, and are they conscious? And what does machine learning mean?

Big data is vast, unwieldy information that is so huge that normal software traditionally used to analyse it just can't cope. It's not new. Ever since humans organised ourselves, we've been keeping records, and gathering information, from scrolls, to bank ledgers and now your internet browsing history. But his information is now flowing into organisations at a faster rate and in greater volume than ever before. Taking a good look at it could provide meaningful insights. But how can you spot patterns in the chaos, without the job taking forever? And what insights could this mega data analysis provide?

You might be wary of using digital currencies, but you probably already do. Salaries, benefits and pensions are now paid direct to banks, and when you buy a coffee, you may well use a contactless card to pay, without a flutter of a 5 pound note in sight. So what are online cryptocurrencies like Bitcoin, and why won't some people touch those with a barge pole? And when you hear about them, another word always pops up - Blockchain. What does it do? And how could both become important when we start to use the next version of the Internet, called web 3.0?

Just by putting on a headset, Virtual Reality promises to immerse you in another world, and Augmented Reality takes that world and brings it into your living room. How do they work? It's a type of technology that seems to have been "the next big thing" for at least a decade. But are they just expensive toys, or do they have a use beyond gaming? In a similar vein, you may have seen adverts for the Metaverse, and that Facebook's parent company is pumping huge amounts of money into it. But what is it? How are Virtual Reality and Augmented Reality linked to the Metaverse, and will they make it...a reality?

We all get that sinking feeling when we accidentally delete a valuable photo or document, but there's now a good chance you can find a backup copy - thanks to the Cloud. Cloud computing has drifted into our lives without many people even realising - apart from those irritating emails, offering to sell you ever greater amounts of storage space. Some laptops now have very little memory built-in, and rely on the Cloud to store files. But where does it all that information go? What does the Cloud look like and where exactly is it? How are vast amounts of computer memory and processing power being put to use? And are those precious photos of your pet cat being kept securely?

From the team behind the hit Radio 4 series Sliced Bread, this is Toast. You can find more episodes in the Sliced Bread feed only on BBC Sounds, or by searching for Toast on BBC Sounds. BBC business journalist Sean Farrington investigates wonder products and businesses which promised so much to consumers... but ultimately ended up as toast. Sean is joined by the self-made millionaire and serial entrepreneur, Sam White, to conclude what went wrong. Together they look at why a product or business failed, and what we can learn from their stories today. In this preview episode, Sean talks about wearable tech and Google Glass. These futuristic looking spectacles, with a heads-up display which showed text messages and street directions and allowed users to record video footage of what was happening around them, were named in Time Magazine as one of the best inventions of 2012. There was plenty of hype. Google even demonstrated them by live-streaming a sky dive using Google Glass. But by 2015, just two years after their release, Google announced that Google Glass Explorer, the consumer version of the glasses, was going to be shelved, and the version used by businesses has since been ditched too. Sean and Sam speak to former BBC technology correspondent Rory Cellan Jones and the 'godfather' of wearable technology Professor Sandy Pentland, from the Massachusetts Institute of Technology, to discover how Google Glass went from being the best thing since sliced bread to toast.

Collectively, our individual financial decisions have a big impact on what the wider economy does. That includes how we manage our own money, including what we buy and how we buy it. One way we make large purchases, smooth out big bills and sometimes just spend some cash we can’t afford - is credit. In this episode Dr Victoria Bateman looks back to the Tallyman in the 19th century, a very early way of shopping with credit. We’ll explore what exactly credit is and how we use it. Everything you need to know about the economy and what it means for you. This podcast will cut through the jargon to bring you clarity and ensure you finally understand all those complicated terms and phrases you hear on the news such as Inflation, GDP, National Debt, energy markets and more. We’ll ensure you understand what’s going on today, why your shopping is getting more expensive or why your pay doesn’t cover your bills.

The rising cost of living really brought home how those big, global economic shocks can mean some pretty bad bumps for our individual finances. Probably the most obvious, immediate and, painful way that global economic events hit our household budgets is through the price of energy. In 2022 we saw our bills almost double - causing the government to step in and guarantee energy prices, with the Treasury picking up the rest of the tab. Even with that support, many people are struggling and we’re all paying a bit more attention to our bills. How does the market for energy work? Exactly what are we paying for, who sets the prices and why are our bills so much higher?

This podcast will cut through the jargon to bring you clarity and ensure you finally understand all those complicated terms and phrases you hear on the news. Inflation, GDP, Interest rates, and bonds, Tim Harford and friends explain them all. We’ll ensure you understand what’s going on today, why your shopping is getting more expensive or why your pay doesn’t cover your bills. We’ll also bring you surprising histories, from the war hungry Kings who have shaped how things are counted today to the greedy merchants flooding Spain with Silver coins. So if your eyes usually glaze over when someone says ‘cutting taxes stimulates growth’, fear no more, we’ve got you covered.
