If you’ve travelled out of a major airport recently you might have seen a hologram providing various instructions. Joanne McNeil did some background research on them:

• The holograms cost the same amount as the annual salary for a customer service representative – and is advertised as working 24 hours a day, 7 days a week, and not requiring a background check.
• The holograms currently loop the same pre-recorded segment over and over, but the companies behind the hologram are developing technologies that will let them respond to questions.
• Those in the holograms are usually professional actors since “facial expressions are everything”. The holograms might outlive the actors as swapping recordings is expensive.
• Soon the holograms might also be seen at doctor’s offices, museums and more.

The full article looks at the societal implications of the holograms, how they work, and what experts have to say about the technology. Read it here.
