How pop science should be written; concise, engaging, illuminating, and compelling.
Thoroughly researched and more balanced that expected, but still problematic. As a librarian/Information Science professional, I have serious qualms with the argument that we should learn to "live" with algorithms/machines controlling functions of society. Yes, I see the benefits and potential. Yes, I agree that better developed algorithms can improve quality of life. But, I think the folks who develop tech often forget that an algorithm (a machine) should never be depended upon to make humane d ...more

We rely on the computers and the internet for almost everything these days, it is the backbone of our infrastructure, our first point of social contact for friends and associates all around the world, supplies our film and music choices and is a substantial part of the economy now. As the digital world permeates our life further computers are being used as part of, or in some cases the entire part of the

Too shallow for anyone who already knows a fair bit about algorithms. I felt (strongly in the Art section) that she wasn't advocating for the programmers and had the perspective of someone who hasn't thought very holistically about human computer interaction. 'Computers can't make art' is a sentiment that really bugs me, it shrouds technology in this cold deific cloak when THE COMPUTER IS THE ART. I so strongly believe that making a computer make art is an extremely artistic endeavour. Go read s ...more

Among all of the staggeringly impressive, mindboggling things that data and statistics can tell me, how it feels to be human isn't one of them.
This is the book I've been searching for, the book I had been hoping for when I read Weapons of Math Destruction: How Big Data Increases Inequality and Threatens Democracy a couple of months ago. Both books cover similar concepts and even examples, but while I found Weapons overly negative and pessimistic, Fry wonderfully covers both the problems and

Not much of a look inside algorithms. I was hoping for more math but I might be in the minority with that.

She’s a personable writer but most of what is collected is just that. A compilation of contemporary observations gleaned from many open sources.

An engagingly written pop science look at algorithms, which is to say the computer codes that now run our lives, from neural networks playing chess and composing Bach to the ones used to diagnose disease or analyse your shopping habits to guess if you're pregnant or serve you up deceptive fake news on Facebook so you vote Brexit.

Some of it is really scary, some of it holds a glimpse of a better future--especially when Fry explains the ways machine intelligence *plus* human insight give the best

We are living in an era that is impossible to imagine a life without machines and algorithms.
good or bad, it all depends on us, it all depends on how to be human in the age of machines.
I am pretty sure that most of us have a wrong understanding of what they are and how we need to deal with them.
so I strongly recommend this book!

I give the book 4 stars for the great content
and one more star because Hannah Fry is a real star.

Fry takes us through an engaging overview of data and algorithms, and how they are used in our modern world.
It reads like an entertaining Guardian article, but never really manages to pull itself to a higher level than that.
Some questionable conclusions are drawn, and there may be a lack of depth on any of the individual subjects, but the occasional nuggets of wisdom and the easy tone make up for much of the downsides; it was still a breezy read and may serve as an interesting introduction to da

Great read! This caught my eye as it was passing through the library on its way to fill a patron’s hold. I think I had algorithms (view spoiler) (view spoiler) on my mind because of the class I’m taking this semester. I can’t say the cover or title is anything that would fill me with excitement—although once she explained the title, it made me smile and say, “Ohhh”—but for whatever reason, I placed a hold for myself.

I know there are a fair amount of books out there about the impending doom/utopic promise of algorithms running our lives. And this is a good one. With humor and intelligent, Fry gives us a nice sampling of all the areas of human existence that are not only being taken over by computer algorithms but the significance and the utility in each case.

Search engines are basically a short cut to authority. "Google it" has become the ultimate rebuttal bulletproof of any further disco

The subtitle is key, because this isn't a book about software engineering. It does not examine the code of algorithms or any complex math. What it does do is discuss how humans and algorithms interact, and it does this beautifully. Interesting, and at times humorous - recommended!

In Hello World, author Hannah Fry examines some algorithms, from chess to criminal justice to art, both successes and failures. As she says in the introduction, this is primarily a book about humans - who we are, where
ash | spaceyreads
Hannah Fry introduces us to algorithms and to thinking about algorithms in her crisp, lighthearted, accessible book. This is definitely something for the uninitiated and may benefit you the most if this is one of your first books about data science. There are no in-depth arguments of any sort, she didn't zero in on any sub-topic; it's a light skim off the frothing issue condensed into something you can read on your commute or before bed.

"It's about asking if an algorithm is having a net bene
In this book, Hannah Fry gives an introduction and overview on algorithms and algorithmic techniques used (or set out for future use) in our modern societies. It starts by explaining basic concepts of machine learning, AI and data-driven algorithms. She then explores different areas of society and life to show that similar techniques can be used in very different contexts, like medicine, cars, the justice system or art. In all of these contexts, she manages to highlight the good, the bad and the ...more

Though roughly enjoyed every chapter, it was absolutely fascinating! Reminded me of reading Atul Gawande or Jon Ronson, such a brilliant blend of passionate narrator, demonstrable excellence and understanding in their field and page turning enthusiasm.

An excellent overview of the past, present and future of how computational algorithms shape our world, from the estimable Dr Hannah Fry.

In seven sections - Power, Data, Justice, Medicine, Cars, Crime & Art - Fry give examples, background, threats and potentials of this incredibly powerful IT tool. The examples are well chosen - some I knew, some were new to me - and she uses each as a jumping-off point to discuss the effect not only of the technology itself, but of the cultural, societal and int

Thought provoking and interesting read delving into our evolving use of algorithms to make decisions in place of and in addition to those we make ourselves. Balanced arguments explore the positives and negatives of this increasing dependence across the topics of power, data, justice, medicine, cars, crime and art. The author takes us on a journey from the beginnings of our capabilities to program machines, through to the emergence of self-driving cars and the recent Cambridge Analytica scandal b ...more

Rivetting. Engaging. Funny.

Hannah Fry takes on the tyrannical influence of algorithms. But doesn't cast a future of doom, sounding like a luddite. The book is a refreshing take on how we could have a framework where we understand and accept AI for its flaws, and make decisions aided by it while questioning its power at each stage.
Kara Babcock
Algorithms are increasingly an important part of our lives, yet even as more of us become aware of this, how much do we actually stop to consider what that means? How much do we stop to consider who is designing these algorithms and how they actually work? And why are we willing to give up so much control to them in the first place? Hello World is a short tour through the various ways in which algorithms intersect with human decision-making. It is neither comprehensive nor particularly in-depth. ...more

A short book written for a non-techie like me, the anecdotes made this a leisurely read – some were very funny – which helped to illustrate the point better. Hannah Fry’s enthusiasm for tech and maths really comes through. I also liked how the book chapters were divided into broad topics, my least favourite was art, I found it to be less comprehensive than the others. The most surprising was how algorithm is used in justice and medicine; I had no idea how they it’s used by judges o

This is a book about the details of how human has entered the age of data. The algorithms that run on data by finding patterns are being used everywhere and have been in use for more than 30 years which is well before the words 'Data' and 'Algorithm' became mainstream. In this book, the author gives brief history along with prospects of the use of data science in several departments. How big companies utilize them for their big profits. Computer and algorithms can be seen as impartial at the sur ...more

I won this book through a Goodreads giveaway and received a copy from WWNorton for review purposes. This does not affect my rating or opinions of this book.

Perhaps the greatest strength of this book is that it was understandable for the layperson with minimal technical experience, but not patronizing or reductive which would alienate a more knowledgeable reader. It's written conversationally, with an occasional witty aside/observation/pop culture reference, but always stays on topic: balancing t

Great writing and very well researched. Looks at algorithms, their effects and the extent to which they should be used in some of the most important areas of life, such as healthcare, crime, justice, cars, art etc. I would say the title is a bit deceiving, as a computer scientist it made me think it was biased against algorithms, but it isn't. It just examines their place in our daily life and considers how much we should be using/trusting them, weighing the pros and cons and their level of "per ...more

Hannah Fry writes in a very human and relatable way about how algorithms have come to play a role into our lives in a variety of different ways. The book is full of interesting anecdotes about how computers play a role in medicine, law, transport and art which are then used to pose interesting ethical and philosophical questions.

It's a quick read and definitely one worth picking up even if you have a passing interest in technology and computer science.

Data Privacy us going to be the biggest issue in upcoming years in developing and under-developed countries. Data is the new currency and it has been shaping our society and our thought process without us paying attention to it. Artificial Intelligence being already used in Criminal Justice System was news to me. The case has been analyzed thoroughly. This is a no-nonsense book about awareness towards digital security.

When should you trust and algorithm over your own judgement? Should judges be replaced by algorithmic models? Do facial recognition algorithms have a net positive outcome in society?

This book sparks a whole lot of dilemmas. It is not a hypothesis of what would occur when AI surpasses human intelligence, but rather how AI is influencing the world we live in right now.

I liked all the chapters, but I couldn’t help disagreeing with the conclusion. I quote: “Perhaps the answer is to design algorithm

I’m in awe with this book!! I found it through goodreads’ suggestions and was a bit skeptical of it being too philosophical and not so much data driven but I was wrong.

Written by a female mathematician - of whom I am a fan of already - this book goes through the great challenges of AI and algorithms in various areas of our lives. In this process, Hannah Fry also explains some important machine learning concepts in a great, simple and light way. My favourite part of it all is her writing is put
