Recent headlines outline something many people aren't happy about: Most recent headline in this vein I saw was some people went to a party, and someone modified all the photos they took at the party to be not real, but of those real people at the party.

... Also, people are increasingly wearing public spy devices like glasses with cameras. Additionally, in some countries many people think it's OK to just photograph anywhere they want (and anyone they want). ... Also, governments are increasingly using cameras to ID citizens at protests etc.

Will we eventually see on the market hats whose brims project holograms over our faces? or collars that project upwards?
