What if we manage to hit The Singularity - that oft-receding target by which your brain's contents can be uploaded to a computer system in the event of (or ahead of) your death?

Wouldn't that be cool? Well, maybe. But more importantly, who's going to pay for it all when we're "dead" (and so presumably not able to earn money any more)? Ah, that's it - advertising will fill the sky and "your brand preferences will be aligned with those of our sponsors".

But wait! What about all those books you remember reading? Oh dear.
