 ## 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`.

+This is also why calling C "portable assembly" may have been appropriate in 1978, but is a dangerously misleading statement nowadays.

 With this, I think we are ready to look at a first draft of my "2018 memory model" (working title ;) -- in the next post. :)
 
 Thanks to @rkruppe and @nagisa for help in finding arguments for why `Uninit` is needed.
