Brotopia: Breaking Up the Boys’ Club of Silicon Valley
Shows how computing went from women's work to a boys' club through a biased 1960s study, stereotypes and copycat hiring. It also explains why tech companies that bring women back in earn and last more.

1. Introduction
1 min 01 sec
If you have ever looked around a tech office and assumed the imbalance was natural, Emily Chang has a correction: the first computer programmers were women. In Brotopia, the longtime Bloomberg Technology anchor traces how a field that once treated programming as women’s work turned into a boys’ club. She shows that people made that shift, and talent had nothing to do with it.
A personality study from the 1960s, toys and films aimed at boys, after-hours deals in hot tubs and hiring by referral each pushed women further out. Chang’s case is that the industry’s male dominance was built step by step. What was built can be redesigned, and the companies willing to do it stand to gain.
Along the way come the numbers that settle an argument in any meeting, from a share of computing degrees that fell from 40 percent to 18, to a funding gap of $58 billion against $1.46 billion.
2. Know who really wrote the first programs
1 min 39 sec
Picture a programmer and a socially awkward young man probably appears. The people who first made computers work looked nothing like that, and one of them compared the job to planning a dinner party.
3. Spot the flawed study behind the nerd stereotype
1 min 44 sec
A software company hired two psychologists to describe the ideal programmer. Their answer rested on one personality trait, and it tilted hiring for decades toward a particular kind of man.
4. Learn how girls were pushed out of computer science
1 min 58 sec
Teenage girls and boys arrived at school with the same computer skills. Within a generation, the share of women earning computing degrees had more than halved, and the cause sat in family purchases and cinema screens.
5. Where after-hours deals leave women behind
1 min 50 sec
In parts of Silicon Valley, important meetings happen in places where a woman loses whether she shows up or stays away. One strip club even earned a nickname that made it sound like office space.
6. Judge the code before you know the coder
1 min 55 sec
When reviewers on one coding platform could not see who wrote the code, women’s work came out ahead. Yet women are still asked to check their code more often, and male-led firms draw a vastly larger share of funding.
7. Break the referral loop that clones your team
1 min 51 sec
A startup proud of hiring only the best mostly hired its founder’s friends. Once a team looks alike, every referral makes it more alike, but one adviser and one company point to ways of interrupting that cycle.
8. Balanced leadership that lifts profits and survival
1 min 56 sec
An online game banned abusive players and watched its audience climb by tens of millions. A study of two million companies points the same way, and a Google engineer’s complaint about women ends up arguing against itself.
9. Conclusion
1 min 16 sec
Brotopia’s strongest move is to take something most people treat as nature and give it a history. Women wrote the early programs. Then a 1960s profile, drawn from 1,378 programmers of whom only 186 were women, defined talent as disliking people. Toys, films and family gifts did the rest, and an industry that hires its friends kept the result in place. None of it needed a conspiracy, only habits that looked fair from the inside.
That history is also the hopeful part, because habits can change. If you review work, look at it before you know whose it is, the way GitHub’s blind comparison did. If you hire, notice where your referrals come from and ask for them from the people who are missing, as Pinterest did. If you plan the client night, pick a place where nobody has to weigh their reputation against the deal. And if you fund or lead a company, remember the two million firms in the International Monetary Fund study, where balance at the top came with better returns.
Grace Hopper once compared programming to hosting a dinner party. The industry spent decades forgetting who first set that table, and it can still invite them back.
About this book
What is this book about?
Look around most tech companies and men far outnumber women. Many people assume that is simply how the field is. Emily Chang, a longtime Bloomberg Technology anchor, shows otherwise. The first computer programmers were women. Then a 1960s personality study, toys and films aimed at boys, and a culture of deals in hot tubs and strip clubs pushed them out. Chang follows the evidence from Grace Hopper and the women behind John Glenn's orbit to Susan Fowler's account of life at Uber. She shows how women's code is doubted even when blind reviews favor it, and how male founders received $58 billion in venture funding in one year against $1.46 billion for women. She also explains how companies like PayPal, sure they hired on merit, ended up cloning their founders' circles. The book then makes the business case. It covers a game that grew by banning abusive players and an International Monetary Fund study of two million companies linking balanced leadership to better returns. Readers come out able to explain how the gap formed, and they get two concrete hiring suggestions plus the business case for diversity.

Top reviews
As a woman who has navigated the labyrinth of Silicon Valley for years, this book felt like a long-overdue validation of my own lived reality. Chang does a phenomenal job of stitching together the disparate threads of sexism into a tapestry that is impossible to ignore. Truth is, many of us have internalized these microaggressions for so long that we stopped seeing them as problems. The reporting on the "good guy" myth was particularly stinging because it perfectly describes the oblivious leaders I work with every day. While some critics argue it’s a rehash, seeing these stories documented with such rigor creates a powerful collective voice. It’s a must-read for anyone who thinks tech is a pure meritocracy. We need this mirror to see the cracks in our culture.
Show moreFinally, someone had the guts to put all of these fragmented news stories into one cohesive, stinging narrative that demands attention. The way Chang connects the dots between the early "hacker" culture and modern-day exclusion is nothing short of brilliant. I appreciated the actionable pathways suggested toward the end, as it moves the conversation from mere complaining to actual reform. It’s an essential report for every hiring manager who wonders why their pipeline lacks diversity. Look, the industry is changing, but it won't happen without the blunt honesty found in these pages. The pacing is excellent, making a dense subject feel like a gripping page-turner. Highly recommended for anyone who cares about the future of innovation.
Show moreWow, what a punch to the gut this was. I listened to the audiobook read by the author, and her passion for the subject really shines through in every sentence. It’s one thing to hear about "bro culture" in passing, but it’s another to see the data and the history laid out so clearly. The title "Brotopia" is perfect because it captures the exclusionary utopia these men have built for themselves at the expense of everyone else. Truth is, I was mad as hell for most of the nine hours. This should be required reading in every computer science department in the country. It offers a necessary reboot for an industry that has lost its way.
Show moreChang’s deep dive into the historical roots of the "antisocial coder" stereotype is absolutely fascinating and provides much-needed context for today’s toxic environment. I was particularly struck by the 1960s history, showing that the gender gap wasn't an accident but a manufactured outcome. The writing is punchy and the pacing keeps you engaged, even when the subject matter makes your blood boil. Personally, I found the analysis of venture capital funding to be the most revealing part of the narrative. To be fair, I wish there were more interviews with mid-level engineers rather than just high-profile CEOs like Sheryl Sandberg. Despite that, the book offers a transparent view of the hurdles women face. It’s a well-crafted wake-up call for the industry.
Show moreThe section detailing the "PayPal Mafia" and their definition of meritocracy really opened my eyes to how the deck is stacked from the start. It’s a sobering look at how the systems built by a small group of men have essentially codified exclusion into the very DNA of the tech world. Chang writes with a lively spirit that makes even the most frustrating anecdotes readable. In my experience, the most powerful parts were the stories of whistleblowers who risked everything to speak out against harassment. I do think the book could have benefited from a broader look at global tech culture instead of just the California bubble. Still, the well-researched content makes it a foundational text for the #metoo era in technology.
Show moreTo be fair, much of this information has been circulating in tech circles for years, yet seeing it compiled so starkly remains a gut-wrenching experience. Chang’s writing is well-crafted, balancing personal anecdotes with broader industry trends in a way that feels both intimate and expansive. I was especially interested in the chapter about managing motherhood and how the "hustle culture" specifically penalizes women. There are minor criticisms to be made about the focus on "big names," but the overall message is too important to ignore. Diverse teams produce better products, and this book explains exactly why we are currently failing to build them. It’s a transparent look at a very ugly reality.
Show moreTruth is, the tech world desperately needed this mirror held up to its face, even if the reflection is quite ugly. Chang provides an essential report on Silicon Valley sexism that feels both urgent and deeply documented. I appreciated how she navigated the complexities of the James Damore situation without being overly dismissive. The book is well-paced and manages to make a lot of complex social issues accessible to a general audience. While I wish there was more discussion on the roots of patriarchal behavior in broader society, the focus on tech remains laser-sharp. It’s a must-read for anyone who believes that what is moral is also ultimately good for business. Let’s hope the disruptors are actually listening.
Show moreWhile the reporting here is undoubtedly vital, I couldn't help but feel it read a bit like a high-end tabloid at times. The focus on the infamous sex parties felt slightly sensationalized, especially when compared to the systemic policy issues that deserve more page time. I wanted more depth on how we can actually dismantle the patriarchal structures of corporate America rather than just another list of SV's greatest hits. To be fair, Chang is a talented journalist and her prose is undeniably fluid. However, the lack of an index for female-friendly resources felt like a missed opportunity to provide a roadmap for change. It’s a decent primer for newcomers, but those already in the trenches might find it a bit surface-level.
Show moreAfter hearing all the buzz, I expected a bit more focus on solutions rather than just a dramatic exposé of problems we already know exist. The stories are powerful, don't get me wrong, but I found myself asking "okay, now what?" several times. Chang mentions the importance of "Girls Who Code," but the ending felt somewhat rushed and lacked a comprehensive strategy for professional women. Look, the reporting on the culture of "meritocracy" is sharp and well-researched, but the lack of diverse perspectives from non-white women was a noticeable gap. It’s a good book to give to a leader who is oblivious, but it might not offer enough new insight for those already working in these environments.
Show moreI picked this up hoping for a rigorous sociological study, but what I got was mostly a collection of Silicon Valley’s most offensive hits. Frankly, if you’ve been reading the news for the last three years, there isn’t much new information here. My biggest issue is that Chang unthinkingly reinforces gender essentialist tropes by suggesting women are naturally more community-oriented. This kind of thinking is exactly what books like "Testosterone Rex" warn against because it validates the status quo. The section on the James Damore memo was a particular letdown, as it failed to provide the hard scientific counter-arguments we actually need. It feels more like a long-form magazine article than a definitive book. It’s disappointing given the hype.

What is Brotopia by Emily Chang about?
Brotopia explains how the tech industry became dominated by men. Chang shows that early programmers were mostly women, then follows the shift: a 1960s study linking programming to disliking people, computers marketed as boys’ toys, a bro culture of deals in hot tubs and strip clubs, and hiring by referral. She ends with the business case for gender balance.
Were the first computer programmers women?
Yes, according to Chang. Early computer work was treated as clerical, so it was seen as women’s work. Women programmed the US Army’s first computer during the Second World War, Grace Hopper programmed the Mark I at Harvard, and three women mathematicians at NASA made John Glenn’s 1962 orbit possible. In 1967 Cosmopolitan even ran a feature called The Computer Girls.
Why did women leave computer science?
Chang points to several forces. A 1960s report by psychologists Cannon and Perry steered hiring toward antisocial men. Computers were then marketed as boys’ toys, bought for sons and celebrated in films like WarGames and Revenge of the Nerds. Women’s share of computer science degrees fell from about 40 percent in 1984 to 18 percent in 2011.
Does gender diversity make tech companies more profitable?
Chang argues it does. An International Monetary Fund study of 2 million European companies found that firms with women in 40 to 60 percent of leadership roles had better financial returns and were less likely to fail. League of Legends grew from 67 million to 100 million monthly users after it began banning abusive players, and women make around 70 to 80 percent of consumer purchases.
How can a company apply the ideas in Brotopia?
The book points to evidence of bias and a few practical hiring steps. A GitHub study showed that women’s code won approval more often than men’s once the coder’s gender was hidden. Ask for referrals from underrepresented groups, as Pinterest did, and follow Joelle Emerson’s advice to hire a diversity-focused head of human resources before reaching 50 employees. Deals often happen in hot tubs or strip clubs, which puts women in a bind about whether to attend.
