My future health care provider might. Maybe they’ll spike rates by figuring out how often I’m ill using this data.
Maybe I will marry a congressman someday and the sext that I sent today to my BF will be used to blackmail us.
Maybe 30 years from now, people will be able to use my youthful indiscretions as leverage.

Maybe my sleeping habits will lead to higher life insurance rates.
Russia and private actors have already personally targeted millions of people using highly directed ads to move an election using publicly available data. Imagine what they could do with Google’s data. Target congressional aides? Target the POTUS’ mistress (or mister)?
In the hands of a Caesar or a Napoleon that data is the power to reshape the Earth, smite your enemies, eviscerate any obstacles and remake the holder into an invincible demi-god.
