Cold approach between our primeval programming and the digital world

John is a web developer, he got his new girlfriend Carla through his social circle, after splitting  with an exotic asian girl, Mei, whoM he met on A dating platform.
What is wrong with this scenario, you might ask?
There is nothing inherently wrong with this scenario, except that it does away with the most important step when meeting people, the first cold encounter.

This greatly limit our choices and mating options. 
It removes the first part out of the equation, which could be equated to giving a martial art athlete the black belt after passing a written or an oral exam.
The first encounter could be anywhere, in the street, in a supermarket or in a gas station.
A guy sees a girl he likes, he goes up to her and introduces himself.
Sounds simple, right?
The simplicity of the operation, belies the complexity of what goes on inside our brains when we decide to perform this deceptively simple act.
This seemingly straightforward interaction triggers an avalanche of neurological processes that our modern lifestyle has left us unprepared for. 

The moment we decide to approach a stranger, our primal threat-detection system activates, flooding our body with stress hormones designed for fight or flight situations. 

Our evolutionary wiring interprets the potential for social rejection as a genuine threat, causing our heart rate to spike, our palms to sweat.

Approaching women from other tribes in past times, especially rival tribes, was considered a fatal transgression, since cross-tribal romantic encounters often resulted in deadly conflict.

Our mind races through catastrophic scenarios and operates through our primeval programming. 

In addition to that, the fundamental human interaction which is the spontaneous encounter between two people has become so foreign owing to the digital media's invasion of our world.

Our natural abilities got blunted and now simple tasks like talking to strangers require an inordinate amount of effort and courage.
