Brave New World
But a Brave New World could lead to an even braver New World, if we so desired. We can create the benevolent Big Sister, one who looks back on the 20th century respectfully, but in dismay. For instance, much funding for such sites clearly comes from advertising revenue. How can we remove advertising from the forums of the future? Personally, I don't want to discuss life, the universe and everything whilst being bombarded by pictures of women wearing underwear that doesn't fit properly. I went into one of those popular lingerie stores once and was disgusted to find that none of the expensive items was well made, or fitted. That implies that their revenue is generated entirely by trend value, gladly paid by women, many of whom are technically living below the poverty line and should be spending the money on more fresh fruit and vegetables.
I don't see why Alexander Grothendieck would want to return from exile.
