I was excited to read the book, because Kaku is a well regarded physicist, and that’s a field that I know will inform what’s possible, technologically, thirty or so years from now. I will admit I did not read the reviews of the book before hitting “purchase” on my Kindle. The topic alone made it worth my time, and the book was on the NYT bestseller list for five weeks, after all. Turns out, the book was worth the time….but perhaps I should have read the reviews so my expectations were more properly set.
I thought I was going to learn some fundamentals about what’s possible in the next few generations, and if you work hard enough, you will learn some of that. But the book reads more like a string of popular science articles meant for a *very* broad audience, and far less like a serious investigation of how physics might inform our world in the coming decades.
The New York Times’ review might sum it best (and I know, it’s a cliche to depend on the Times, but…it pretty much sums up my thoughts on the book):
“…Mr. Kaku thinks in numbers better than he thinks in words, which is a problem only in that he’s written a book and not a series of equations….This is not boring stuff, and it all somewhat makes me wish that I (born in 1965) were going to be around to witness it all. In terms of data delivery, “Physics of the Future” gets the job done. But airplane food gets the job done, too, and airplane food — bland and damp — is what Mr. Kaku’s prose too often resembles.”
Ouch. I hope I never get a review like that. But then again, I rarely think in numbers.
Kaku does not lack for ambition – he sets out to explain, in great detail, how we will live in 2100, and how we’ll get there. But he often uses the conditional tense, and swaps between “this might happen” to “this will certainly happen,” sometimes on the same page. It makes for a general lack of trust when it comes to whether or not you want to buy into his proclamations. He also leans heavily on a thesis he calls “The Cave Man Principle,” which, to simplify, says that we are still pretty much driven by the same impulses we had when we lived in caves. The idea gets old and is often used as a salve when the future starts to get hard to predict. He also loves to drop pop culture references – in particular to sci fi movies – as a way to explain how things might shape up. I’m not sure I’d want Hollywood to loom that large in *my* future…
Still, if you are looking for a relatively fast read that covers a lot of ground around flying cars, the Internet on contact lenses, and palm sized MRI machines, this book is worth a look, despite the sometimes artless prose. Better yet, however, I’d recommend you watch a few of Kaku’s television shows (he’s made a number of them for Discovery Channel, among others), and we’ve enjoyed watching those as a family.
I’m still reading Kevin’s “What Technology Wants,” which so far I’m really enjoying. Hope to write about that shortly.
