Last time I looked, more than 13,000 people had signed an online petition calling for British computing pioneer Alan Turing to be depicted on the next version of the £10 note.
That's not quite as many as signed the one calling for the government to issue Turing with a posthumous pardon, but its chances of success seem about as promising. Which is to say, sadly, not very.
This isn't perhaps that surprising. Turing is an awkward figure for the British establishment.
His achievements and monumental contribution to the discipline of computer science are brushed under the carpet, not least because his prosecution on the grounds of his sexuality and subsequent suicide don't exactly paint the establishment in a flattering light.
But the main reason that the petition is likely to fail is also much more obvious. Turing simply isn't widely enough known.
The current figure adorning the Bank of England's tenner is Charles Darwin. Now, it's pointless trying to compare the achievements of these two great men: both were responsible for remarkable advances in their respective fields.
But in a popularity contest there would be only one winner. My mother would instantly know who Darwin was and why he is remembered. Turing? Not so much.
Frankly, I don't regard that as a failing of my mother, who's an estimable woman in her own right. I think she's probably typical of the wider public in not appreciating the debt of gratitude we all owe Alan Turing.
