Of course it's nowhere near ready....but it IS coming. And it will change...EVERYTHING.
Look at the "Will Smith Eating Spaghetti" video and then look at what they can make just a year later.
My nephew is five. He already has no concept of "broadcast" television. TV is just this thing you turn on and then you have infinite choices at your fingertips.
Kids born today aren't going to have a concept of what "making a movie" means.
"Wait, you're saying you had to get a bunch of people together in the SAME room, with costumes, and they had to act things out? Why?? That's ridiculous!"
Yeah... future filmmaking -- not all, but much -- will be more like animation... artists may look at it like painting.
A single person will be able to make a movie, just like a single person can write a book. It will be the "new visual novels" of a future generation. The new graphic novel. And its not that far away. 10-20 years.
the problem is getting consistent results. it's really really hard to get consistent exact results.
