AI doesn't "understand" anything. Whatever else one might think about AI, none of the models we have today are anywhere near "thinking" machines. They are predictive machines at best, spitting our own knowledge back at us.
Time travel doesn't exist because time travel wiped out the timelines where it did

A problem with the Many Worlds interpretation is that it would take infinite energy to create that many timelines.
The only way I see that time travel can be a thing is by properly set up wormholes and only in self-consistent travels. In other words, time travels that won't alter the past.

Which means only travel to the future, with no potential to interact with the past.
Imagine you opened a stargate to a planet 5 light years away, 100 years in the future. An astronomer could pass through the gate and use very sensitive telescopes to detect the composition of Earth's atmosphere (for example) 5 years in their past aka 95 years in Earth's future. If they showed the people on Earth's side of the stargate the data, Earth could respond by making different choices about pollution, thereby changing the past of the astronomer. So in order to avoid paradox, any stargate technology must not be able to act like a window.
Well, it already takes infinite enegy to create the universe we have, so that's not really a problem.
