Hey, if Dr. Tattoff can remove tattos with a laser somebody will make rewritable lasers like DVD-RW! Maybe not infinite rewrites but it's possible.

Anyone see Blade Runner? There was a chinese guy who is the eyeball making specialist.

Recently I saw a story that scientists are growing livers for transplant. I'd like an eyeball upgrade. Maybe one that doesn't fatigue as easily as my default parts.

As much fun as it is to speculate about the ultimate invincibility of science, I would like to point out that the key to writable and re-writable CDs and DVDs is the dye, not the laser. That after all the selection pressure the eye has gone through, it also happened to be made of a re-writable dye of any sort seems rather improbable.
