I just ran into this prediction of Smalltalk adoption:

“The latest figures I’ve heard are that Smalltalk has between 15% and 25% of the entire OO market, but is growing at about 60% per year, while C++ is only growing at about 30% per year. If these trends continue (of course, they never *exactly* do), Smalltalk should overtake C++ by the end of the century!” 

This was posted to comp.lang.smalltalk on May 11, 1995. Last time I checked, the 20th century ended, C++ was still going strong and Smalltalk was blindsided by Java. What does that say about future predictions?
