…But they also predict that in the future everyone is going to be “lifelogging” — continually recording images from their vacations, conversations from business meetings, and even intimate confessions to friends….
Lifeloggers trace their history back to 1945, when Vannevar Bush, a prominent American scientist, wrote an essay for The Atlantic Monthly called “As We May Think.” Scientists deal with an increasingly unmanageable trove of data and other information, Mr. Bush wrote, but technology could help. Mr. Bush imagined scientists wearing little cameras on their heads to record lab work. He conjured an image of a desklike machine that could store thousands of pages a day in microfilm. He called his device a memory extender, or “memex” — a term that some researchers use today to describe their own suite of lifelogging tools.
Anyone who has ever thought seriously about privacy would shudder at the thought of a lifelogged world, Mr. Rosen says. “The standard techno-positivist enthusiasm — that this is inevitable and that we should get used to it — is wrong and dramatically understates the social cost of this sort of technology,” he says. Louis Brandeis, the Supreme Court justice who wrote the most famous treatise on privacy in American law, “would be turning over in his grave,” Mr. Rosen says.
