Imagine watching a collage video of the first times you met every person in your life. The clips of first encounters would play back-to-back, in chronological order.
Not many people would be willing to commit to a lifelong lifestyle of wearable cameras. Some would.
At the very least this would be entertaining to watch. Both for the main protagonist and anyone that knows what the video/story is about.
Re-watch the first time you met your loved ones.
This video collection would be a treasure in old age when the memories fade.
This is not for everyone. Not many people would have the discipline/commitment to follow through from birth. If the project lasted from birth, people would need help from their parents to get them started.
For those that have what it takes there are various ways of going about it. The one that might get the least amount of pushback from society is if someone first starts recording these videos as an art collection.
There are people that commit to decades long projects. For example, here is a guy that takes a photo of himself every day, for 20 years. I imagine this video means the most to the guy in it, but judging by the number of views on that video, people find the project worthy of their time. There are others that had some help from their parents to get their streak started. I imagine that people in both examples will continue the streak until they die. I would:)
Lifestyle with wearable cameras
You never know when you are going to meet someone. If you want authentic first-meeting videos, you need to record everything, before it happens. This would require a lifelong commitment. A lifestyle of wearable cameras and batteries. This would be like Truman's show from first person's view, minus the streaming.
You also never know which angle the next person you meet will come from, so a 360 or at least 180 degrees camera would be suitable.
When the technology advances the cameras would get smaller and higher quality. The batteries would get lighter and stronger.
People have attempted live streaming of their lives (lifecasting) before.
I imagine a commitment like this wouldn't be too hard for someone who tapped into their OCD to keep them going. Video sorting/editing would take a toll on someone's time.
Tags and classifications of people
If you took the time and classified each person by how close you are, and sorted them in various categories, the software could create different collages:
how you met all the people you love
everyone that had a decisive impact on your life
everyone that brought business opportunities
everyone that you trust
everyone that trusts you
Capturing moments worthy of remembering
Since you're recording everything anyway, you might as well sort/save different events. Not just first meetings.
After something important just unfolded, the camera wearer should have an easy way to bookmark the event as important, to be editer/reviewed/categorized later. I imagine something like pressing a button on the camera and adding a voice memo that gets transcribed into text and sent to your sorting software along with the video section.
When you have time, you sit down at your workstation and go through the videos. When you're done editing/taging the video gets saved in the cloud forever. People pre-pay the cloud storage for years in advance. If they find it valuable, their children and grand children can someday pay to keep the cloud going.
Privacy, security, and legality
I understand that this would be a nightmare from the perspective of other people's privacy. Unauthorized access to this sounds like big brother's wet dreams.
I don't have a solution for this concern. Maybe things will drastically change in the future and this won't be an issue anymore. For now, whoever goes for this project will probably need to get everyone's consent. This could be an interesting conversation opener.
