Great Upload
From Tardis Wiki, the free Doctor Who reference
The Great Upload took place on 30 December in 9,000,000,000, with the descendants of the human race uploading their consciousnesses to the cloud. They downloaded into bipedal meat bodies 500,000 years later. (PROSE: Time Traveller's Diary [+]Loading...["Time Traveller's Diary (novel)"]) The Tenth Doctor was aware that humans spent a million years as downloads before reverting to "the same basic shape" which they ultimately held by the end of the universe in the year 100,000,000,000,000.
