The most efficient computer possible already exists. And no, it’s not

a Mac or a PC - it’s the human brain. When
computers were originally invented, they were
designed around a brain model. At one time,
many even referred to them as electronic brains.
Indeed, it is certainly impressive how today’s
computers can emulate single brain functions,

Nonetheless, scientists around the world
continue to be inspired by the brain and strive to
mimic its abilities in the development of
technology. Neuroscientists now know that the
mind operates by evaluating the state of thousands of synaptic connections at a time
and computes with patterns of neural activity that are not readily associated with
numbers.

HDC (hyper dimensional computing) is an emerging computational paradigm that
aims to mimic attributes of the human brain’s neuronal circuits such as hyper-
dimensionality, fully distributed holographic representation, and
(pseudo)randomness. What science has discovered is that an HDC framework
functions exceptionally well within an in-memory computing architecture

While our brain operates by evaluating the state of thousands of synaptic connections
at a time and computes with seemingly arbitrary patterns of neural activity, HDC
models these neural activity patterns of the brain’s circuits in the form of high-
dimensional vectors called hyper-vectors that operate on a rich form of algebra that
defines rules to build, bind, and bundle them.
