Strewth, the thing that prompted me to write this review, apart from actually reading the darn book, was the terrible incident that brought down the Virgin Galactic test flight in California this weekend. Even though I'm unlikely to be able to afford the initial fees ( ~£250K ) for a flight, I'd still volunteer to fly with VG or, in the future, any other service offering spaceflight, even after these most recent and horrendous events.
For me, humankind absolutely must break free of the boundaries of this single planet. As an IT consultant, I know about Single Points of Failure or, as my granny would've said, putting all of ones eggs in a single basket.
Therefore, space travel MUST form part of our future, hopefully sooner rather than later, partly to give humanity an outlet to a Plan B ( and Plan C and Plan D .... ) future, and also to help remove the resource constraints under which we've placed ourselves.
Some of the stories in Project Hieroglyph make this very very clear. The solar system, let alone the rest of the universe, is a resource-rich environment, and we've known since the 1940s that the first 100 miles ( or so ) are the hardest.
Let's get out there .......
