In honour of H. Karamanian (from whom I didn't manage to find any quotations):
"Where a calculator on the ENIAC is equpped with 18,000 vaccuum tubes and weighs 30 tons, computers in the future may have only 1,000 vaccuum tubes and perhaps weigh 1 1/2 tons." -- unknown writer in Popular Mechanics, March 1949
"It would appear that we have reached the limits of what it is possible to achieve with computer technology, although one should be careful with such statements, as they tend to sound pretty silly in 5 years." -- John Von Neumann (ca. 1949)
