I would agree with Tamir. I think that the solution is to make sure that the law is grounded in principles rather than details and minutiae. Looking at the necessity requirement as well will help, because regardless of what technology was used to collect a piece of information, it's still helpful to ask, do we need it? Was it collected appropriately? Was it collected properly? The idea of appropriately and properly may change versus the technology, but the concepts of needing to know for sure that we've done things based on these core principles doesn't change and allows us to be flexible and keep the law relevant as things change.
