It's not bad but it's not really my thing. A lot of it seems to be him tooting his own horn, he talks about how people were concerned that his amazing fame would spin his head and he wouldn't survive it, which I found a little funny because I'd never heard of him, so you can probably guess I'm not really the intended target, i.e., someone who is all in on "design." I mean I've never even taken a single class on design, although I am vaguely interested in it. When flipping through the book, it seemed like I'd love it, but in actually reading it, it...wasn't that interesting, really.
I started reading it from the front, got about a section and a half in, was underwhelmed, then started to treat it like a coffee table book and skipped around sections and "essays" but was also underwhelmed. I would say in all I probably read about a quarter of it. Main takeaway is this guy is super far up design's ass. Not trying to be critical, we all have our preferred lens(es), and that's his, and it seems to serve him well. The book itself is visually appealing, fun to hold and flip through, so at least it seems like he knows what he's talking about there. But it does sort of feel like... all design, no substance. It seems like this is book hits really well for its intended audience, though, so if you're a design person, you might want to check it out. It's probably just me who doesn't "get it."
