The 5th amendment protects evidence inside the brain of the accused. As devices becomes more and more an extension of the brain, the more I think we'll need to adjust the rule of the 5th amendment to cover things outside of the brain.
Think about what we want as a society though. If you did commit a crime, we want to convict you. The reason the 5th protects you from compelled self-incrimination is to prevent unjust interrogation and investigation techniques from the cops[0], not to make the overall likelihood of conviction lower, although it incidentally has this effect. From a policy standpoint the ideal world would be one where all criminals are…
That's a massive assumption in an age when there is a law, somewhere, that make you and me criminals. It's a small ask for laws that are impractical to enforce remain impractical.
