Will be a quarter century old in 5 years. AES came out when? Standardized in 2001 after a 5-year process by NIST. OpenSSL finally made it to 1.0 this year after a 12 year stint at 0.9.X (it sat at 0.9.8 for 5 years). Amazingly enough, they're all pretty much still going strong - mostly because the crypto field moves pretty damned slowly. The general philosophy in crypto isn't "It will be ancient in 5 years", it's "we won't even trust it for live deployment until good people have bashed it for a decade".

Moore's Law doesn't move *that* fast. What was the fastest commercially available processor in 2005? What is it today? What gain was there over the last 5 years, and is there reason to expect the next 5 to be any different? More to the point - most mobile phones use ARM processors to keep the power consumption down. As a result, they're a tad slower than what you'll find in desktops and servers (hint - how well would your cell phone work if it had to carrry around the heat sink a Core2 Duo needs?). And what good drugs are you on that you think a cell phone processor 5 years from now will have the CPU power that current moby-cluster supercomputers have? (If we're on the verge of making those sort of advances, I want to see what a Sony Playstation 4 can do in 2015. Yowza - holodeck time. ;) Might be more cost-efficient to get to the holodeck using the drugs you're on thought. ;)
