Is there any technology to predict the future now? Not the kind of divination! ! ! !

I suggest you read kevin kelly's book Necessities. After reading it, you will understand how to predict the future technology.

And your metaphor obviously doesn't mean that. The technical prediction of the former is based on the existing technology and has scientific basis, but it cannot be realized due to the current technical bottleneck; Moreover, the pupils at the back said that there was a scientific basis for taking the exam in Tsinghua Peking University.
