Thanks, Ozawa-san. Well spotted! So what does this tell us? There is nothing really new in life - Moore's Law is true, but is just a way of raising the cycle of repetition up another quantum layer. An alternative explanation is that when Anne wrote that famous "SOA has croaked" article at the beginning of the year, she had merely revived the corpse of Wainewright's long-dead sceptical analysis. It's all about timing!!!
