Science fiction anthology with a variety of tales to suit a variety of tastes. In 'Tom' by Paul Cornell, marine aliens arrive and make themselves at home, much like dolphins that can live on land too, and we go and clean up the seas. Gated communities live expensively in domes while poor people and eco-terrorists gather outside; self-replicating nano-machines which gobble up an oil spill and just keep going threaten Earth and for some reason all the people with autism are to be sent away and saved.
Some stories are very old themes, like people who meet up in online game lives and never in RL, and time travel, and a spaceship disaster. If anything has changed, it is the language and assumed technology making them more modern in feel. People studying Lincoln via time travel add the data to Wikipedia. A forest has turned semi-sentient and defends itself against people due to genetic manipulation; references are made to China's one child policy, the Sentient Equal Rights Act, to Hillary Clinton.
Norman Spinrad is the best-known name, and he contributes a brief story about interstellar travel, a narration of a science and a journey but sadly lacking any characters. Other contributors include an Indian woman with a PhD in physics and a woman who runs a witchcrafting supply store in England. Several authors have been nominated for various SF awards, some have won, and Allen Steele we are told in 2001, testified before the U.S. House of Representatives in hearings regarding the future of space exploration. SF has always tried to imagine and address challenges for us, and SOLARIS RISING, edited by Ian Whates, is good dip-into reading, though no tale is long enough to address a subject in any length. I didn't take to some of the tales or styles, but we're all different.
