So my thought/theory/musing was this:
In the not too distant future when we (the human race) have finally managed to create Quantum Computing and are the proud owners of machines that can compute an infinite number of calculations in the blink of an eye. A future where everything we feel,touch, taste, smell, see and hear can be directly recorded onto our various personal devices that are now just permanently attached and part of our bodies.
Imagine then, if you will, that at some point after recording all this data for some time you decide that something you did in the past, you did incorrectly and would like to change your actions to re design your future.
By voluntarily hooking yourself up to a quantum computer device that can interact directly with the devices in you body and brain you could in theory rewind through the recoded data to the point just before this incorrect action happened then allow the quantum computer to carry out running the data from that point but allowing you to change the event to how you wish and therefore 'Change' your own history.
The down side to this would be that you would now exist in a computer generated alternate universe while your real body would exist in our reality as a lifeless shell hooked up to a machine. For your alternate reality to continue down its new path you would have to choose to stay in the simulation and forego the "real world".
This begs the question of would the simulated world be any less real than our reality? I look at this and think that if the human mind could be stimulated in a way to make a simulated reality feel real then it couldn't be anything but real in our minds.
Obviously this theory relies heavily on the future development of quantum computing and other tech advances but in my mind we are on the right path for these things to become tangible.
How would this give rise to the birth of AI?
Once hooked up and inside the quantum computer generated alternate reality you would play out your existence. In this reality at some point you or someone you know will more than likely have a child. This child will be a complete fabrication of the simulation but a fully functioning member of the simulated reality and therefore would have to be AI created by the quantum computer.
Yes it all sounds a bit matrix-y but I do feel that tech is advancing at a rate that would make this all possible in the not too distant future and to me seems like a plausible way to time travel, so long as it is to a past point that has been completely documented and recorded according to your senses and brain activity.
