Public relations is all about relationships, and Collision offers conversations you can’t find at many other tech shows. We met entrepreneurs, visionaries, and leaders face to face, talking about everything from world-changing technology to devices that makes our lives a little better.

On days two and three of the show, we met some wonderful people and saw some incredible tech, from autonomous agriculture to VR surgery simulators.

We even collided with founders and startups we met at Collision last year. The relationships are stronger, the learning experiences greater because of the people we met and the speakers we heard from.

Here’s what we were talking about:

1. Virtual reality.

2. Robots.

3. Artificial intelligence.

4. Smart homes.

5. (Social) Media.
