The interesting thing about that book is that there are two versions that are significantly different, the wikipedia page "The Road Ahead (Gates Book)" describes this quite well (20,000 words were added mostly regarding the internet). The original version stated "today's Internet is not the information highway I imagine, although you can think of it as the beginning of the highway". Before publication Gates realized the internet was gaining critical mass and he redirected the company to become internet-focused. And then the new version of the book was created.
