Also last I checked, the 4th Amendment prohibits unreasonable searches (I would think searching/fishing for elements in the data through autonomous systems, is still called "searching", no?) and seizures (i.e. collections).
It has never prohibited the government from doing other searches, otherwise government agencies would not be able to subpoena business records about you from third parties.
Sometimes Congress passes separate laws adding a specific requirement to obtain a warrant before doing a certain type of search, and the Supreme Court has also acted to expand 4th Amendment protections to include 'reasonable expectation of privacy' (concerning a phone booth conversation in an otherwise public place) but even in that case the Supreme Court specifically abrogated the concept of a general "right to privacy".
Either way if the failure of the Fourth Amendment to be protective enough is that bad then the solution is either to pass a law adding the needed protection (what Congress did for landline wiretaps) or to wait for an activist judge to quote James Madison in a ruling that expands the permit of the Fourth Amendment (e.g. the ruling today).
But simply wishing that the Fourth Amendment says something other than what it does, doesn't turn the Fourth Amendment into what you wish.
