Each person in the world with a handheld calculator would still take decades to do the same calculations Blue Gene is now able to do every second. Rather ambiguous, that. But I can understand how an innumerate "journalist" might think it would take "decades" for a single person to perform 40-50,000 floating-point additions or multiplications with the aid of a calculator. Even if you assume it talks about the population of the world who now possesses a calculator, I still think they could put in 280 trillion operations in under a year.
