Ask HN: What are the implications of Apple moving to 64-bit architecture?

They're planning ahead for http://en.wikipedia.org/wiki/Year_2038_problem

NSDate is luckily already using 64bit precision, so every current iOS device should be able to keep ticking seconds _far_ into the future.

Worsened security; they have 32 bits more to secure. I have no doubts it will be a lot easier for developers to jailbreak it with this new architecture.

For those not in on the joke, ASLR on 64-bit is actually a lot better than on 32-bit; https://en.wikipedia.org/wiki/Address_space_layout_randomiza...

Unless apps and browser plugins appear which weaken ASLR, like several recent versions of DropBox in 32-bit & 64-bit DLLs, Windows 7 x64 SP1 - http://codeinsecurity.wordpress.com/2013/09/09/installing-dr... How vulnerable is ASLR in OSX?
