No machine or robot will replace or imitate what abilities the brain have.

We humans have something that ordinary robots don't and that is called self-awareness and consciousness.

We have our past lifes and future ones and our present in front of us.

We are not just living beings in this life, we have been living beings in the past lifes.

And we have the potential to discover our past life and perhaps our own future maybe even communicate wiith our future self. Artificial Intelligence doesn't have self-awareness or consciousness and it doens't have a past or a future.

Creating Robots/Machines that does the basics of human beings is possible but creating feelings for Artificial Intelligence is totally impossible. Maybe there is a chance to create robots like them but creating robots that are creative in their own ways is impossible.

If we compare every computer, cell phone, laptop and server that is connected to the internet today, to the human brain, there are some similarities at the moment, there is 8 terrabytes per second of data going around the internet, that is the whole of the library of congress every two seconds, it would have 9 exobytes of storage space (1,000,000,000,000,000,000 bytes) there is 55 million links on the internet, that is close to the amount of synapses in the human brain.. So my point, to even closely mimic the human brain, you would need all the power of every piece of electronic equipment in the world, and 5% of the world's power.. A hefty price?

However, artificial intelligence can take shortcuts, what we perceive as artificial intelligence will always just be lines of code, executing one after the other and computers today will only do what is told of them to do in their code, it doesn't matter even if you did get the required computational power -you would still need to write a code-

Science today has only just begun to understand the human brain, and is nowhere near certain on how it all works, how are we conscious? why do we think? why do we have emotions? Science cannot currently understand that, so we would have no hope of replicating it with ones and zeros!

You could say that in the future we will understand our brains perfectly, and computers will have become much smaller and more powerful, but even then.. How do you tell a computer to think?
