64 Bits are Overrated

"I think they are doing a marketing gimmick. There's zero benefit a consumer gets from that. Predominantly... you need it for memory addressability beyond 4GB. That's it. You don't really need it for performance, and the kinds of applications that 64-bit get used in mostly are large, server-class applications." -- Anand Chandrasekher

most desktop apps never use more than 1 gigabyte of memory (mostly due to the von-neumann bottleneck). And 32bit still allows using more than 4 gigs of memory:

So basically 64 bits just waste transistors.

You guys could stop wasting your time and learn something like category theory instead of learning what SO-DIMM means or what's going on with computing hardware manufacture. Until the day comes when you are actually truly building and soldering your own computer etc like it was done in the 70s/80s for PCs then who gives a shit?
