In the information age, personalization and customization are remarkable themes in technology, goods, and services. There is no one brand of toothpaste, or one kind of refrigerator — there are hundreds of each. There is no one kind of phone — there are hundreds of them, each able to be tailored with cases, covers, backgrounds, and apps.
And now, there are even designer babies: Parents are able to choose their children’s hair and eye color (though according to Wired, the Los Angeles clinic offering these services was recently shut down amid public outcry).
The potential for humans to modulate their emotions via technology is just as radical.
