Thanks for joining us at Cold Case Chrissianity, I'm J. Warner Wallace.

I want to talk tonight about three ways that social media has changed our priorities.

And this is true of probably of any technology over time.

Let's face it, we are usually changed by the kinds of new technology that appear on the horizon.

Let's face it, we were probably much more regional, much more geographically located

before the arrival of automobile transportation.

That transportation changed our sense of mobility around the country.

It changed our sense of, it changed the nature of cities.

If you look at the cities that were constructed on the east coast before the invention of the automobile,

they're all vertical cities, right, with mass transit.

You get to California, we have one of those cities called San Francisco.

That's a pre-car city, but Los Angeles is post-car.

And that car, the invention of the automobile, meant that we didn't have to be tightly aligned

in high-rise buildings with close to all the same amenities connected by rapid transit.

Instead, we could be all across the county and we could just drive where we needed to go.

So suddenly cities became much more horizontal and much less vertical.

What's happening here? Well, a way we live, how we live, how we think has been changed by technology.

This happens for every generation.
