CrashCat had a good point.
“It’s the final solution, at least for the lifetime of everyone reading this blog post today.”
Note that you’re talking about problems addressing 4GB in 2007, and also quote Ian Griffiths mentioning how the 8086 (designed in 1976) had to carve up 1MB. If that growth rate were to continue, we’d be looking at addressing 16TB in another 31 years. Of course we won’t be using Vista then. (We aren’t really using it now but that’s another topic.)
I suspect it will be a lot less than 31 years until we see wide consumer adoption of some kind of terabyte-level optical memory or something else that leaves Moore’s Law in the dust.
