B'coz White Box testing tests the unit of code / program  where as Black Box testing has nothing to do with the internal code all it does is based upon expected output it test the system.

So in any case none of them will be replaced by the other.
Based on the testing requirement respective tests needs to be done.

when u perform white box testing we cheek the internal logic of the code and we know that the code is working properly in black box testing just we are combing the diffrant modules and cheek that all the modules are integrated properly and valiadate the results

when u perform white box testing we are giveing input data and validating the out put results we know that what exactly the code is doing

In black box testing we valiadte the just output results we donot what is the code is doing

Example for white box testing

Writeing a program and executing the program

Black box means runing the programing some one is written

Though white box  method of test design can uncover an overwhelming number of test cases, it might not detect unimplemented parts of the specification or missing requirements. But you can be sure that all paths through the test object are executed

We cant run the whole application with the BVA, EP, Decision table, Error Guessing with Black box Testing techniques. To ensure the test is covered with Branch, statement, Path condition with test data to thorughly run. This can be done through by White Box Testing. The tester chooses test case inputs to exercise paths through the code and determines the appropriate outputs.
