I think other authors have done a better job with postulating advances in technology. A few examples:
Charles Stross - Accelerando - One of the more believable and compelling projections of computer tech that I've read in a long time.
Linda Nagata - Vast - Similar projections for computer tech as above, plus genetic engineering. This was a recent random find in a used book store for me, and apparently the fourth book in a series called The Nanotech Succession. I will definitely be looking for more of her stuff.
Paolo Bacigalupi - The Windup Girl - Definitely the best I've seen for projection in biotech, and it hit me in a similar way as the first time I read Neuromancer a few decades ago. Definitely not for children, though. Pump Six And Other Stories is a collection of short stories set in the same world, but I don't know how well they would hold up on their own without the deeper context that TWG provides.
