Often, we are under this notion that digital computation bests human cognition in every possible way–but how?

To start with, computers are powerful, precise, and reliable. They are powerful enough to do computations faster than entire armies of individuals. Whenever a computer goes wrong, the blame is put on humans since they programmed it that way.
In any case, in some critical aspects, the human brain remains to be the best computing device in the world. Humans are particularly great at distinguishing patterns and improvising within indistinct conditions — far more viably than even the most powerful AIs available. Furthermore, using just 22 watts of power to operate (about half that of a laptop), the brain energy-efficiency is unrivaled when it comes to certain tasks.
Neuromorphic computing alludes to the scaffold between the relative strengths and shortcomings of the human brain and present-day computer processors. It is an interdisciplinary field that unravels the powers of software engineering, electrical engineering, and cognitive neuroscience, and endeavors to make processors that work progressively like the human brain by falsely mirroring the human nervous system. In this way, researchers aim to create processors that are both more powerful and more energy-efficient than anything in the market.
Working of Neuromorphic Computing
But the technology has proven theoretically feasible, and if you believe some experts, practical applications are only a matter of time.
The concept of neuromorphic computing was spearheaded by Caltech teacher Carver Mead during the 1980s. In any case, neuromorphic figuring (also alluded to as neuromorphic engineering) is still in its nascent stages yet continually evolving, and just over the most recent couple of years, it has become feasible for business use cases.
To imitate the human brain and nervous system, researchers and scientists are building artificial neural systems that replace neurotransmitters with nodes. One of the hindrances to these systems is the binary nature held by digital processing. CPUs send messages through circuits that are either on or off; there is no space for degrees of subtlety.
Unexpectedly, engineers tackled this issue by returning to simple circuits, or basically analog circuits. Accordingly, they have manufactured processors that can moderate the amount of current flowing between nodes, like the fluctuating electric impulses in the brain that structure and modify brain chemistry.
In terms of power, the most powerful neuromorphic processor available in the market stimulates a notable 16 billion synapses — however, it’s still long ways from the brain’s 800 trillion. This type of processor holds an imperceptibly small piece of the market and is mostly proposed for research and defense purposes. Yet, the innovation has proven hypothetically feasible, and scientists are to be believed, real-life applications are only a matter of time.
Solving Issues with Neuromorphic Computing
Uncertainty: At present, standard computational processes are excellent at performing explicit tasks, such as analyzing situations under plainly characterized circumstances. Neuromorphic computing seeks to improve computers with respect to processing power and uncertainty. That implies managing probabilities as opposed to deterministic models, which in turn requires analog transistors that can express beyond binary options. […]
