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.
