Book review: An Optimist's Tour of the Future
Mark Stevenson Profile, £12.99
IT IS BECOMING increasingly difficult to distinguish between magazines like New Scientist and magazines like SFX.
Given that nowadays most of us have a device remarkably similar to a Star Trek communicator - and one, moreover, that doesn't require Lieutenant Uhura on the bridge acting as exchange operator - the conceit of this book is neat: how science-fictional is our future going to be?
Beginning with mid-life-ish musings on personal mortality, the book ventures into the life expectancy of the planet as a whole.
Stevenson interviews leading figures in fields such as transhumanism (with particular emphasis on life extension), cybernetics, genomics, nanotechnology, artificial intelligence and a variety of climate change experts, ending up with the most famous futurologist, Ray Kurzweil.
He insists that the optimism of the title was prompted by his agent; but throughout his moderately interesting tour, a kind of rose mist tends to descend.
There are remarkable scientific discoveries and technological advances described in this book, and it's rather too easy to get swept along on a tidal wave of giddy, geeky thrills.
Stevenson tends to downplay some of the more cautionary tales: such as that of Jesse Gelsinger, an early volunteer for gene therapy who died within four days of treatment.
It doesn't help that Stevenson has an inappropriate, wise-cracking levity throughout (comparing Gelsinger's death with the successful treatment of Corey Hass, he quotes Hass's father - "they've changed my son's life forever" - then comments "there again, Jesse Gelsinger's father could say the same"). The choice of a present tense, overt first person narration conspires to make the book sound like the voice-over on a Channel Five documentary.
And there are enough needling inaccuracies - the solar power pioneer Augustin Mouchot was not patronised by Napoleon, but Napoleon III; the claim that there were no systems of public education before the 19th century rings hollow in Scotland - to undermine any confidence in the conclusions.
But it's the ethical side-step that most unsettled me. If we can extend life, whose lives will be extended - even with Obama's health care reforms? The blue-collar worker or the millionaire? Will medical advances benefit the healers or the plastic surgeons?
And there's one very odd omission in this book: quantum computing. Of all the speculative changes, it's the one with most to offer and the most tantalising early successes. But quantum physics might be a bit too mathematical for this jaunt.
