In our world today, technology of choice is used to rationalize love. There are sites everywhere like eHarmony that has you create a profile and then allows you to search others who fit the mold you want them to. You can find them based on looks, age, jobs, wages and anything else you can think of. Then there are apps like tinder that while you don't search for specifics, you still decide who you want to talk to based on their pictures or profile. There are algorithms behind all of these sites that find your tendencies and start showing more people who fit them.
