Not really, as zeckalpha pointed out, this is quoted out of context and was talking about OpenText:

"The difference between Google's advertisements and OpenText's is Google (usually) identifies advertisements as advertisements."

Also, Google results have gotten significantly better than they were in 1998 so even if we ignore the OpenText context, I don't see how this could be a successful prediction as you're trying to imply.

I think he forgot the sarcasm tag, but it's hard to tell.

First and foremost it's off-topic. Second, these are the same citations used by those who were pushing for the FTC to sue Google for antitrust, so they have political baggage, third: it's before the company was founded so it's all academic and theoretical with no actual experience behind it, fourth: context matters - choice quotes from long texts have been used for Google bashing before, some earlier this week even.
