The girl from the future

I saw this advertisement some time ago, and I can't get it out of my mind. It showed a blue-haired girl (no, it wasn't Marge Simpson) who supposedly came from the future, and had brought a revolutionary washing powder with her. Each time I saw the ad, I thought to myself, "hey, hold on a minute. She has come from the future and all she has got to show us is a bloody box of washing powder?" This girl comes from the far future, maybe centuries away from us, from a world with an advanced society where scientists must have found a cure for every known illness, where they must have found solutions to the problems we have today... and she comes here just to show us what the washing powder of the future will look like? She must come from a world where there is no AIDS, no cancer and no Alzheimer, where they have found the secret of eternal youth, where they have a remedy for the ever-increasing hole in the ozone layer, where natural resources are plenty and available to every human being, where they have developed new energy sources; still, she wants to tell us about washing powder. What on earth is she thinking about? Well, maybe in a century or two, washing powder will be as valuable as gold, or even more valuable than that, who knows... But if we ask the woman in the advert (the one that receives the unexpected visit of the blue-haired girl from the future), who is busy trying to remove some stain from her laundry, I'm sure that she would rather get some other piece of information instead: the following week's winning lotto numbers, for instance? Seriously, this really drives me up the wall...
