Pessimists perceive a dumbing down that spread users too thin, resulting in shallowness that could be lethal to politics, to clear thinking. Is Google making us stupid? Let's weigh the evidence.

Surveillance. It is used by every tyranny to lock in place an uneven arrangement of power. When the mighty know all about you but common folk know little in reverse, then without accountability you can only have despotism, as shown by 6,000 years of recorded history. But new technologies do not have to lock in perpetual Big Brother. The spread of tools like cheap cameras and instant sharing might lead to the antidote against Big Brother. That is, if we learn the lessons taught by both history and science.

Historians have long studied how civilizations rise and fall. But today it isn't just social collapse that makes thoughtful people fret but a potential end to everything.

To tumble back down into entropy. So, want to have some fun listing and weighing all the ways (that we know) the universe could have it in for us?

Prescient and scientifically accurate, Heart of the Comet is known as one of the great hard SF novels of the 1980s. First published in 1986, it tells the story of an ambitious manned mission to visit Halley's Comet, alter its orbit, and mine it for resources. But all too soon, native cells - that might once have brought life to Earth - begin colonizing the colonists. As factions battle over the comet's future - and that of Earth - only love, courage, and ingenuity can avert disaster and spark a new human destiny.
