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?

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 our jobs under threat, or is it much worse than that? And before we get to the destruction of humanity, 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.

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?

Do you know your Blockchain from your Bitcoin, or your Virtual reality from your Augmented Reality? Are you clueless about AI but are worried it might take your job?

If so, you’ve come to the right place.

Welcome to Understand: Tech and AI.

The pace of change in technology is daunting - and new developments are happening all the time. Artificial Intelligence has exploded into the public consciousness. So it’s ever-more important for us to understand where these technological enhancements are coming from and how we can best use them.

In each episode we'll demystify all the technology that’s become part of all our daily lives, and take the sting out of those buzzwords that tech companies are so fond of.

On Understand Tech and AI we’ll take one concept per episode, explain what it is and what it does - without any technical jargon - so that you can get a better grasp of the technology that’s in your hand, on your desk or in your living room.

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? And where did it all begin: economic historian Dr Victoria Bateman gives us a brief history of the National Grid.

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 cost of living crisis is putting more pressure on more people - but what happens when that pressure becomes too much, and is bankruptcy always a bad thing? Professor Diane Coyle explains the processes and wider economic impact of bankruptcy, and Dr Victoria Bateman takes us back to the very beginning of the idea in the time of Henry VIII.

Politicians talk about government debt a lot. When Prime Minister Rishi Sunak promised to tackle Britain's five most pressing problems, he included making sure our debt was falling. But what is the debt? In this episode Dr Gemma Tetlow explains why we have the debt at all, how much we owe, who we owe it to, and whether we should worry about it. Plus Dr Victoria Bateman takes us back in time to hear about historical debts we are still repaying today.
