You can hardly avoid hearing about AI today. You see AI in the movies, in books, in the news, and online. AI is part of robots, self-driving (SD) cars, drones, medical systems, online shopping sites, and all sorts of other technologies that affect your daily life in so many ways. Some people have come to trust AIs so much, that they fall asleep while their SD cars take them to their destination — illegally, of course (see “Tesla driver found asleep at wheel of self-driving car doing 150km/h” at The Guardian.com.)
Many pundits are burying you in information (and disinformation) about AI, too. Some see AI as cute and fuzzy; others see it as a potential mass murderer of the human race. The problem with being so loaded down with information in so many ways is that you struggle to separate what’s real from what is simply the product of an overactive imagination. Just how far can you trust your AI, anyway? Much of the hype about AI originates from the excessive and unrealistic expectations of scientists, entrepreneurs, and businesspersons. Artificial Intelligence For Dummies, 2nd Edition is the book you need if you feel as if you really don’t know anything about a technology that purports to be an essential element of your life.
Using various media as a starting point, you might notice that most of the useful technologies are almost boring. Certainly, no one gushes over them. AI is like that: so ubiquitous as to be humdrum. You’re using AI in some way today; in fact, you probably rely on AI in many different ways — you just don’t notice it because it’s so mundane. This book makes you aware of these very real and essential uses of AI. A smart thermostat for your home may not sound very exciting, but it’s an incredibly practical use for a technology that has some people running for the hills in terror.
This book also covers the really cool uses for AI. For example, you may not know there is a medical monitoring device that can actually predict when you might have a heart problem, but such a device exists. AI powers drones, drives cars, and makes all sorts of robots possible. You see AI used today in all sorts of space applications, and AI figures prominently in all the space adventures humans will have tomorrow.
In contrast to many books on the topic, Artificial Intelligence For Dummies, 2nd Edition also tells you the truth about where and how AI can’t work. In fact, AI will never be able to engage in certain essential activities and tasks, and won’t be able to do other ones until far into the future. Some people try to tell you that these activities are possible for AI, but this book tells you why they can’t work, clearing away all the hype that has kept you in the dark about AI. You also discover potential security issues in using AI and the kinds of hardware that work best for implementing it. One takeaway from this book is that humans will always be important. In fact, if anything, AI makes humans even more important because AI helps humans excel in ways that you frankly might not be able to imagine.
About This Book
Artificial Intelligence For Dummies, 2nd Edition starts by helping you understand AI, especially what AI needs to work and why it has failed in the past. You also discover the basis for some of the issues with AI today and how those issues might prove to be nearly impossible to solve in some cases. Of course, along with the issues, you also discover the fixes for some problems and consider where scientists are taking AI in search of answers. Most important, you discover where AI is falling short and where it excels. You likely won’t have an SD car anytime soon, and that vacation in space will have to wait. On the other hand, you find that telepresence can help people stay in their homes when they might otherwise need to go to a hospital or nursing home.
For a technology to survive, it must have a group of solid applications that actually work. It also must provide a payback to investors with the foresight to invest in the technology. In the past, AI failed to achieve critical success because it lacked some of these features. AI also suffered from being ahead of its time: True AI needed to wait for the current hardware to actually succeed. Today, you can find AI used in various computer applications and to automate processes. It’s also relied on heavily in the medical field and to help improve human interaction. AI is also related to data analysis, machine learning, and deep learning. Sometimes these terms can prove confusing, so one of the reasons to read this book is to discover how these technologies interconnect.
This book also contains an extraordinary number of links to external information (hundreds, in fact) because AI has become such a huge and complex topic. These links provide you with additional information that just won’t fit in the book but that you really do need to know to gain a full appreciation of just how astounding the impact of AI is on your daily life. Many of the links are embedded in the name of the article, and print readers can search for them using your favorite search engine; e-book readers can simply click the links. Many other links use what is called a TinyURL (https://tinyurl.com/). The reason for using a TinyURL is that the original link is too long and confusing to type into a search engine without the risk of errors. If you want to check a TinyURL to make sure it’s real, you can use the preview feature by adding the word preview as part of the link, like this: https://preview.tinyurl.com/pd88943u.
AI has a truly bright future today because it has become an essential technology. This book also shows you the paths that AI is likely to follow in the future. The various trends discussed in this book are based on what people are actually trying to do now. The new technology hasn’t succeeded yet, but because people are working on it, it does have a good chance of success at some point.
To make absorbing the concepts even easier, this book uses the following conventions:
· Web addresses appear in monofont. If you're reading a digital version of this book on a device connected to the Internet, note that you can click the web address to visit that website, like this: www.dummies.com. Many article titles of additional resources also appear as clickable links.
· Words in italics are defined inline as special terms that you should remember. You see these words used (and sometimes misused) in many different ways in the press and other media, such as movies. Knowing the meaning of these terms can help you clear away some of the hype surrounding AI.

Where to Go from Here
It’s time to start discovering AI and see what it can do for you. If you don’t know anything about AI, start with Chapter 1. You may not want to read every chapter in the book, but starting with Chapter 1 helps you understand AI basics that you need when working through other places in the book.
If your main goal in reading this book is to build knowledge of where AI is used today, start with Chapter 5. The materials in Part 2 help you see where AI is used today.
Readers who have a bit more advanced knowledge of AI can start with Chapter 9. Part 3 of this book contains the most advanced material that you’ll encounter. If you don’t want to know how AI works at a low level (not as a developer, but simply as someone interested in AI), you might decide to skip this part of the book.
Okay, so you want to know the super fantastic ways in which people are either using AI today or will use AI in the future. If that’s the case, start with Chapter 12. All of Parts 4 and 5 show you the incredible ways in which AI is used without forcing you to deal with piles of hype as a result. The information in Part 4 focuses on hardware that relies on AI, and the material in Part 5 focuses more on futuristic uses of AI.
