This story was really well written and I certainly don't regret listening to it. But I wasn't so keen on the world building....
1) It's a mildly depressing thought, but I tend to believe that most corporate leaders are more intelligent than myself. (Hence why they're leaders in a very competitive market). They're also ruthlessly pragmatic. As such, I found it difficult to believe that they would just passively watch the world collapse, rather than turn off the ad fairies. Previously 'evil' companies like McDonald's are becoming more and more 'responsible' as time goes on. This is because a) If consumers think you're evil, they're less likely to buy you product (I would have thought the protests/boycotts/bombings would have started when Malls started brain scanning. This world seemed considerably more relaxed than the one I live in) and b) You resource/income base needs to be sustainable for long term profit - e.g it's a bad idea to kill off your consumers.
2) Where the hell did the money come from. These people are addicts, using credit to pay for goods. But credit card companies only profit when you pay them back, which tends not to happen when you die. I realise this was a world where essentially economic collapse had happened, as a result of the adverts. But even before the collapse, where on earth did the cash come from? I mean, a mall in every town requires some serious resources.....
3) Reflective lenses in your glasses. Bet ya $50 they're released two days after the ad-faeries.
I realise that this is essentially nit-picking and normally I hate those who do it. I mean, come on, most sci-fi requires some suspension of disbelief. But I thought I'd rain down on this parade, since everyone else seems to love this story. And as I stated at the start, I did enjoy it. And I'm pretty sure the 15 year old version of me would have loved it. But right now he thinks I'm a sellout and is refusing to talk to me, so I'm not certain.
