It seems no one dares to go further than 150 years in the future. That's strange because on a podcast I heard an astronomer say that the Earth would be habitable for another 500 000 000 years (after which the sun's life cycle will make things too hot). 500 million years will be enough for civilization to start over
many times, if necessary. And considering that the dino's are only gone for 65 million years, 500 million is enough for the apes to take over :)
