Those predictions are a lot less impressive if you read the text of them rather than a short summary written after 2009 came to pass. The prediction about portable computers for 2009 that he
actually made back in 1999 (in the book
The Age of Spiritual Machines) reads:
"Personal computers with high-resolution visual displays come in a range of sizes, from those small enough to be embedded in clothing and jewelry up to the size of a thin book."
People don't really use wearable computers now, at least not powerful enough to drive high-resolution displays. And the desktop is still with us, as are laptops in the same large form factors that were all that was available in 1990.
Looking at his other predictions for 2009, I'm not sure its fair to say that cables are disapearing since you still need them for the highest speed connections, but the statement is ambiguous enough that I'll give him that one.
"The Majority of text is created using continuous speech recognition" is totally false.
"Most routine business transactions take place between a human and a virtual personality. Often the virtual personality includes an animated visual presence that looks like a human face." No.
"Intelligent courseware has emerged as a common means of learning". Sure, but I'd already done this back in '99 so it wasn't a hard prediction.
"Pocket sized reading machines for the blind" AFAIK these exist.
"Translating telephones are commonly used for many language pairs" well, its in development. I imagine it'll be common by 2015.
"Widespread deflation" well, both the US and Japan have had bouts of deflation recently, that wasn't due to technology but rather central bank decisions.
"The neo-Ludite movement is growing" its less of a problem than in 1999, as far as I can tell.
If you look at all his predictions rather than cherry picking the best ones and rewriting the rest to sound better he doesn't come out so well.
