The brain of octopus is very developed, can it surpass humans and become intelligent creatures?

When it comes to octopus, everyone may think that it is just an ordinary food. However, from the perspective of the neural structure of the brain, it is much more powerful than humans. Octopus has 3 hearts, 1 main brain and 8 complex brains, as well as two sets of memory systems, and there are 500 million neurons in the brain. The unique neural structure of the octopus makes it have the ability to think beyond that of ordinary animals.

A scientist once did an interesting test. They stuffed an octopus into a bottle and then spun the bottle cap around a few times to cover it. At first, the octopus tried to use the tentacles to open the bottle cap, but later found that it couldn't work and changed the way. I saw that the octopus used the suction cup on the tentacle to suck the bottle cap and turn it continuously, and finally escaped. This fully illustrates that octopuses, possessing "conceptual intelligence", are able to solve some complex things on their own. So some people wonder, since octopuses have a more powerful and complex brain neural structure than humans, why did they not evolve into intelligent creatures?

Compared with other animals, although octopus is very intelligent, its physiological structure does not support it to become intelligent creatures. Octopus is a cephalopod. Although its physiological characteristics allow it to have certain advantages in marine survival, it is still at a great disadvantage compared to vertebrates on land. For example, short lifespan and lack of intergenerational communication between populations. And octopuses are invertebrates, except for tentacles, in fact, it is not flexible. Octopuses use water jet propulsion to swim, moving very slowly, and to swim in this way, the energy invested far exceeds the kinetic energy generated. In other words, if there are no tentacles, octopus hunting is difficult.

The innate conditions of octopus cannot allow it to become an intelligent life, not even the overlord of the ocean. In addition to its small size, octopuses also lack heme, and other organisms have extremely high oxygen digestion rates. Because of this, octopuses do not have the ability to compete with other fish sports.

And the most important point is that it is very difficult to create civilization in the ocean. If octopuses want to create civilization, they must evolve from the ocean to land. Because it is underwater, it is difficult to carry out related production construction activities. If an octopus establishes a civilization in the ocean, it cannot use fire, and therefore cannot develop a metallurgical technique. In addition, steam engines cannot be used. Steam engines are a necessary step for the development of industrialized civilization. It is impossible for octopuses to establish civilization in the ocean to achieve major breakthroughs in industrialization and high-tech fields.

The smart brain of octopus was evolved as early as 65 million years ago, and humans didn't know where it was at that time. From tens of millions of years ago to the present, in this long period of time, many creatures have evolved from head to toe, but the brain of octopuses has not undergone substantial changes.

If octopuses want to be intelligent creatures, a smart brain is not enough. If octopuses do not undergo genetic changes, it is difficult to stand on the same level as humans. However, this possibility cannot be completely ruled out, but from the current point of view, it is still very far away for octopuses to become intelligent life and create civilization. If one day, octopuses evolve into intelligent creatures through evolution, humans may have immigrated to space. And most importantly, if octopuses want to catch up, they must get the consent of humans. But will humans give them such a chance?
