in 1 bilion years , i dont think huamns wil be around ,a t least not in the way we imagine our selfs , i imagine long before then slight mutations in teh gene pool wil long ago turned us into a difernt species by the time we see 1 billion , that is assuming that we don't expire altogether/0hich is the most likely outcome , given the fact that the longest living speices ever discoverd was a dinosaur and even it didnt see the rise and fall of dinosuar 's on the whole , an entire kingdom of animals that only saw roughly 100 milion years before going extinct, us humans on the other hand have only been aroud a very very tiny fraction of that time (llik 20,000-30,000 years) so yeah i'd say wea re eitehr going to go extinct or be acomopletely new species by that time , which in that case whe wouldn't care about ahving 1 bnillion year old tech, if we are extinct , i guess waht ever creature evolves intelligence in that time frame could learn alot aobut us, Dog and or cat men perhaps ?
