No they have not all "moved on to 64 bits." Most programs work
perfectly fine as 32-bit applications and have no need for the ability
to access a full 64-bit address space. In fact many programs perform
objectively worse as 64-bit application since pointers and data
structures become larger without a corresponding benefit. This is
especially true for mobile applications.

Rumors of 32-bit apps' demise are greatly exaggerated.
