If 3D space can be packed into a 2D hologram, then, can that 2D data be packed into a 1D hologram and so on?

  The article touches on that:
  In recent years, they’ve started to get more creative. Susskind and other teams have made progress [link] on holographic de Sitter models [link] that differ radically from AdS/CFT. Instead of squashing a volume into an area, these universes seem to cram all the dimensions into a lone quantum point.
