Agreed.

I suppose that depends on what you mean by "unaligned".

For example, as I understand it x86 and x86_64 support accessing
words at odd addresses in hardware, using the same CPU instructions
as an aligned access but executing more slowly.  If you want
to extract a 32-bit value from an odd address, and you know
you're running on an x86 or x86_64 and you're not concerned with
portability, you might as well use a word move instruction in
assembly or a simple assignment in C++.  You *could* break it down
into byte moves, but the resulting code would be slower.

For some CPUs, aligned access gives you better performance, but
unaligned access still works.  For others, unaligned access just goes
kablooie.
