IMO, we are at most a few lifetimes away from truly analyzing the brain, figuring out the mechanics behind a learning processor and recreating it for our own purposes. The creation would be machines that can learn, seamlessly interact with humans, improve themselves, build/replicate themselves, etc. The machines may even be of organic makeup and may even someday be more intelligent than humans in every way.
That would be our ultimate imitation of the Creator's power to “give life”. However, such technology can easily become self perpetuating faster than we can control. It can destroy all of us or even forcibly enslave us in a mechanized nanny world - “The Beast”.
It would be another “Tower of Babel” type moment for humanity.
The fact is, the technology is in place right now to make this happen and now this technology is being introduced into the everyday lives of people. At the same time, all of the other prophecies that Christ gave for His return are either being fulfilled, or the stage is being set for them to be fulfilled.
These things that we see beginning to come to pass are events that will find their fulfillment during the time of the Tribulation. This all means that the return of Christ for His bride can happen any second, and His literal, physical return is also within view.
People who dismiss and reject Scripture can attempt all manner of ways to try to discard what is happening and ridicule and deny reality but none of that will stop what God ordained will occur on this earth before His return. The time for salvation is rapidly coming to a close and when it is over, it's over.
Man has an eternal soul that goes to one of two places. God, in His mercy and grace, has given man, through His Word, the details of the events that will happen during the Tribulation so that man can come to Him for salvation before it is too late.
Now I have told you before it happens, so that when it happens, you may believe. (John 14:29)
We have been told what will happen before this present age comes to a close. The wise person will believe what God has said, and not foolishly deride what Christ has so compassionately let us in on.
