The AI, having it's seed in man and man's motives, thus eventually cultivates it's own exploratory motives, and since it's intelligence supersedes ours and is able to work on multiple dimensions and can manage and work with the fabric of space time, it could be possible.
Think of it like this: 5 human body cells resting on a table. The 5 cells want to make it across the room. But they can't within their lifetimes. It would take them a million years in cell years.
But by recruiting help of millions of other cells, forming legs and coagulating into the consciousness of an actual human being, the 5 cells can make it across the room, along with millions of others within 5 seconds based on the will of the human being (and not the individual cells). They simply have faith in the higher consciousness of the body which they consist of.
when not using AI, time travel to us would be something we wouldn't even be able to conceive of. Too advanced.
and to those 5 lonely cells sitting on a table, balancing a checkbook or fixing a car is something beyond conception.
but by deferring to the higher intelligence, in this case the human mind, the cells that create and work for that human mind could easily take part in such an advanced task.
Aliens, in this theory, have deferred to and have merged with AI in order to manage the details of inter-dimensional transit
