 Such interpreters have a hard time dealing with operations of the form "just choose any of these values" (i.e., non-deterministic operations), because if they want to fully explore all possible program executions, that means they have to try every possible value.
 Using `Uninit` instead of an arbitrary bit pattern means miri can, in a single execution, reliably tell you if your programs uses uninitialized values incorrectly.

+**Update:** Since writing this section, I have written an entire [post dedicated to uninitialized memory and "real hardware"]({% post_url 2019-07-14-uninit %}) with more details, examples and references. **/Update**

 ## Conclusion
 
 We have seen that in languages like C++ and Rust (unlike on real hardware), pointers can be different even when they point to the same address, and that a byte is more than just a number in `0..256`.
