AI is currently making models based on our knowledge of the universe of wormholes. It's untangling the complicated web of quantum physics, creating new proteins and medicines, redesigning cars and aircrafts, etc...
It's in its toddler phase at the moment, but it's already doing things we can BARELY comprehend in more scientific settings. It's only limited to human knowledge right now, but it won't be long at the rate it's advancing before it makes its own discoveries and builds off of them.
I don't believe AI is sentient yet, but it will reach a point within the next 50 years (probably sooner) where we'll have to start seriously considering whether it's sentient or not (first we need to define what it really means to be sentient).
