Ain't nothing like the real thing
On the flip, I will say that there are some situations in which using dating apps takes the stress off of dating. For starters, it proves the point that there really are other fish in the sea. Thousands, nay, MILLIONS of other fish in the sea. So if one falls through, worry not! Another is just a few more swipes away.
And as great as that might be for those of us who tend to put all of our eggs in one basket, we lose a lot with that as well.
Nothing can replace the electric spark from meeting someone in person. It spreads from the pit of your stomach out through your fingers -- and definitely through your erogenous zones. Crushing, and everything that comes with it, is an irreplaceable feeling. Which brings me to a bigger, more philosophical point...
Dating is an investment. To meet someone in person takes time, effort, thought, and yes, can ultimately end in disappointment. Millennials don't handle disappointment well. Nor do we know how to be patient. We've grown up in a world where options are endless and everything is available at our fingertips. Media, socialization, banking, food, and now even sex are streaming 24/7.
