“Suffice it to say that we won’t be running out of physical or virtual address space on 64-bit operating systems for the forseeable future. It’s the final solution, at least for the lifetime of everyone reading this blog post today”
Eh? I remember when the Mac II came out, the article in MacWorld being amazed at the vast 4 gigabyte address range addressible by its 32 bit processor and proclaiming that we’d never hit that limit. Not to mention the old (if apocryphal) 640k-should-be-enough-for-anyone chestnut. You’re falling into the same trap.
Starting with 4GB, and assuming Moore’s Law holds constant, we hit 8192GB in 16 and a half years. I’m 27 now, and I damn sure intend to still be alive when I’m 44.
