A City on Mars: Imagining a Human Future on the Red Planet

This was a fascinating look into the near future. The statistic that we will soon have more grandparents than grandchildren really stuck with me. It’s a fundamental shift that will change everything from housing to healthcare. Guillén writes in a way that is very impactful without being overly academic or dry. I personally felt that his 'lateral thinking' approach is exactly what we need in a world that’s changing this fast. The book is well-researched and covers a lot of ground, including some great insights into the 'sharing economy.' It really made me rethink how I'm planning for my own retirement and what the world might look like for the next generation. Highly recommended for anyone who wants to stay ahead of the curve.

Wow. Just wow. I didn't realize how much the world was changing right under our noses. The chapter on the 'sharing economy' and 'Neo-Marxism' was provocative in all the right ways. Guillén uses clear, simple language to explain really complex global shifts. I loved the focus on the three T’s: Talent, Tolerance, and Technology. It’s a very optimistic book, which I think we need right now. It might not be for everyone, especially if you hate economics, but I found it incredibly impactful. It has totally changed how I look at my career and my investments. The clock is ticking, and this book gave me the tools to start preparing for 2030 today.

Guillén has undertaken a daunting task and succeeded in making it accessible. The way he explains the collision of these trends—how aging populations in the West will rely on the growth of the middle class in the East—is brilliant. I personally appreciated the 'lateral thinking' advice at the end. It's practical stuff for entrepreneurs and anyone trying to navigate a gig-heavy world. Some might say it’s too optimistic, but I found the perspective refreshing. It’s a well-researched, interesting read that doesn't get bogged down in too much technical jargon. Definitely one of the better 'future' books I've read in a long time. It really makes you think about the legacy we're leaving.

I honestly found 2030 to be a pretty eye-opening read, even if some of the concepts felt familiar. Guillén does a fantastic job of weaving together diverse threads like declining birth rates and the massive shift in wealth toward women. It’s not just about tech; it’s about the human element of economics. I particularly liked the section on how the middle class is exploding in Asia and Africa while stagnating here in the West. It makes you realize how much our worldview is still stuck in the 20th century. The writing style is very accessible, which I appreciated, although it occasionally felt like he was rushing through complex topics to keep the pace up. If you're looking for a solid overview of where we're headed, this is a great starting point.

A very timely and thoughtful contribution to the genre. What I liked most was that Guillén doesn't just focus on the 'flashy' stuff like AI and robots. Instead, he looks at the quiet shifts in demographics and wealth that are going to hit us like a tidal wave. The postscript about the pandemic was especially helpful; it shows how COVID-119 acted as an accelerator for many of these trends. I did feel that some chapters were a bit repetitive, and he relies heavily on anecdotes that don't always feel fully fleshed out. Still, it’s a very readable book that provides a great overview of the challenges we’re about to face. It’s a solid 4 stars from me.

I received this as a gift and I'm glad I read it. The author makes a compelling case for why the 'rules of the game' are changing permanently. The shift of the global market toward Asian and African consumers is something we really need to start paying more attention to in the West. I found the writing style to be punchy and engaging, though some sentences were a bit long-winded. Honestly, it’s a bit scary to think that 2030 is only a few years away and we are still arguing about old-world problems. This book is a much-needed wake-up call. It’s not perfect—some of the claims about women’s happiness seemed based on shaky data—but the overall message is very powerful.

As a market researcher, I might not be the target audience for this book. Most of the demographic trends regarding the aging population and declining fertility are things I deal with daily. That said, I did find the section on cryptocurrency and blockchain applications to be quite well-researched. Guillén’s take on how blockchain could help with things like gun control or protecting endangered species was a creative touch I hadn't considered. However, the book's reliance on 'lateral thinking' felt a bit like a self-help gimmick by the end. It’s a decent overview for a casual reader, but if you’re already immersed in global economics, you probably won’t find many 'aha!' moments.

Eh. This wasn't exactly what I expected. I was hoping for more of a 'crystal ball' look at daily life in 2030, but it felt more like a textbook on global economics. Personally, I found the chapters on fertility and the middle class a bit slow, though the section on women owning more than half of the world's wealth by 2030 was definitely interesting. I felt like the author was a bit of a 'cockeyed optimist,' which is fine, but it occasionally felt like he was ignoring the massive downsides of these trends. The mention of Airbnb as a disruptor felt a bit dated given everything that’s happened recently, but I suppose that’s the risk with books about the future. It’s okay, just not my favorite.

I wanted to like this, but it felt incredibly US-centric and a bit disorganized. The title promises a deep dive into the year 2030, but it mostly feels like a collection of current events and buzzwords like the 'gig economy' and 'AI' thrown into a blender. Honestly, reading it felt like being at a party where everyone is slightly drunk and trying to sound smarter than they are by quoting headlines. He compares urbanization numbers from 1969 to 2020 without adjusting for the global population doubling, which felt like bending statistics to fit a specific narrative. I also found the constant personal testimonials a bit distracting and superficial. It might work for someone who doesn't follow the news at all, but for me, there was nothing truly revolutionary here.

This book felt rushed. The author bombards you with viral buzzwords—nanotechnology, gender pay gap, climate change—without ever really going deep into any of them. I felt like I was reading a collection of LinkedIn articles rather than a cohesive book. There were moments where he would jump from talking about urbanization to suddenly discussing cancer treatments, and the connection just wasn't there. Also, as someone living outside the US, the American-centric bias was pretty distracting. He ignores a lot of the great work done by people like Hans Rosling or Yuval Noah Harari, which makes his own conclusions feel less authoritative. If you want a real analysis of the future, look elsewhere.
