How Much Computing Power Does Earth Possess and Can It Simulate a Human Brain?

[aquaregia]

Does anyone know of a good estimate of the computing power of all the computers that are on Earth and running.

Do you know how large of a biological brain it would be possible to simulate with all this computing power (eg. 100 billion neurons, 500 billion neurons, ect.)? It seems like it would be possible to simulate like a super huge brain with as much computing power as there is on the planet.

sounds like a "fermi problem"...

I can say that estimating the total computing power of all the computers on Earth is a complex and constantly evolving task. With the rapid advancements in technology and the constant addition of new devices, it is difficult to provide a precise number. However, according to a study by International Data Corporation, the total computing power of all devices in the world is expected to reach 175 zettabytes by 2025.

As for simulating a biological brain with this computing power, it would depend on various factors such as the level of detail and complexity of the simulation. The human brain has approximately 86 billion neurons, but each neuron has thousands of connections, making the total number of connections in the brain in the trillions. Therefore, simulating a human brain with all its complexities would require a tremendous amount of computing power, which may not be achievable even with all the computing power on Earth.

However, it is possible to simulate a simplified version of a brain with a smaller number of neurons and connections using the current computing power. This has been done in various research studies to understand the functioning of the brain and its processes. With continued advancements in technology, it is possible that we may be able to simulate larger and more complex brains in the future.
