Or By Using Litecoin We Can Save Our Crypto-Independence!
Litecoin doesn't help. It modified the normal scrypt behavior for inexplicable reasons to use only a very tiny amount of memory compared to the scrypt paper recommendations. It's quite easy to throw 128k of sram on a chip and scream out one cycle/hash. You'd get an even bigger speedup over GPUs and CPUs than you get from Bitcoin.
Is it possible to use scrypt with memory requirement linked to difficulty? This could be GPU and ASIC-resistant forever.
