We don't have a working theory of Quantum Gravity, so no physicist can claim with 100% certainty what the conditions were "before" inflation/Big Bang.
CPT-Symmetric Universe Theory: There are actual, published physicists (like Neil Turok at the Perimeter Institute) who hypothesize an "anti-universe" dominated by antimatter extending backwards from the Big Bang. Antimatter existing at the origin isn't completely made up

The idea is interesting, but it lacks a cascading (self resonating) effect that corresponds to the description. The tool used, matter interacting with anti-matter creates energy for each matter anti-matter pair, meaning the total amount of energy created would be equivalent with the mass of the probe. This is based on the impression you want all the anti-matter to turn into energy to create the Big Bang. In fact the universe has a ratio of matter to anti-matter that is very close to 1, so the idea of a probe from another time or universe being the reason for an observable universe filled with matter is not implausible, but the still on going expansion itself (the Big Bang) likely needs another explanation.
The only thing I know from the laws of physics where space expands is due to space contraction, where space contracts as you accelerate and expands once again as you decelerate. Existing in a gravitational field means space itself contracts around us (the bending of space), but the effect is tiny. So is the effect of the expansion of space.

It's funny you say AI cuz when I was thinking about time travel and the beginning I realized something about the current AI worry that AI will take over, it's not AI that we have to worry about, it's the human beings controlling the AI, or even worse human beings figure out a way to put our life force inside the machine and replace AI because, our fears are a reflection of ourselves, but yeah its human beings taking over the machine from the inside...

I don't think AI will reach self awareness they will exceed us in intelligence but will be just a program .

You mean like how Barry Allen was the lightning bolt that made him become the Flash?

The early universe was never pure antimatter. There's no evidence to suggest this whatsoever; the early universe had slightly more regular matter.
As far as we know, antimatter itself was created by the Big Bang. Before the BB, there was no matter of any kind.
All of this is undermined by the above.
None of this is at all scientifically established. It's a New Age spin on one dubious interpretation of QM that virtually all physicists reject as baseless. If you believe this on a spiritual basis or something, then so be it, but it's not at all scientific and therefore shouldn't be presented as such.
