Among the many people I admire in this world are the ones who do cool things with old video games. Here's a wonderful YouTube video chronicling in minute detail the things people have done to shave a fraction of a second off their time in a Super Mario Bros speedrun. It's awesome.
Incidentally, although Sonic the Hedgehog is better than Mario in every way, Mario's more fun to do speedrun things with. But the point is, this is exactly the kind of thing people do with the speed cards memory record, except it's all happening in our heads instead of on a TV screen for everyone to see. We definitely need to invent some sort of mind-projecting device if we're ever going to make memory competitions as cool and popular among the nerds of the world as it deserves to be!
