This calls out a really interesting extrapolation of privacy laws that have existed for many years.

For a long time, I (as a human) have permission to watch people around me.

I also have the legal right to record what is happening around me (many states only require one people to be aware of recording activities)

I also have the legal right to record YOU, assuming we are in a location where I can lawfully stand. And I can tell other people what I saw.

Now, I can put a camera somewhere, record EVERYONE, track people, and sell that tracking information.

All because we didn't anticipate the computing potential to record and process EVERYTHING.
