Shakespeare or Einstein, who will you resurrect if you can resurrect only one?
To be, or not to be, that is the question.

Shakespeare and Einstein are sitting together in heaven.
Einstein: Dear Shakespeare, I hear they are voting to resurrect us. Would you like to go back?
Shakespeare: To be, or not to be, that is the question.
Einstein: ???

Einstein: People nowadays live with anxiety and are always hating each other. They need poetry and the faraway land. You should go back.
Shakespeare: No, no, I heard that physics has stagnated now, and there has been no revolutionary progress for a long time. Humanity needs you, so you should go back.
Einstein: Each generation has its own mission, and my mission has been accomplished. The next step is for the younger generation to take. Besides, I’m playing hide-and-seek with Newton.
At the same time, the voice of Newton was heard in the distance. Newton was seen standing on a one-square-meter tile.

Newton shouted: Shakespeare, guess who I am now?
Shakespeare: You’re Newton.
Einstein: Haha, you’re wrong. He’s standing on a one-square-meter tile, so it’s N/m² . It’s Pascals now!
Shakespeare: To be, or not to be, that is the question.

Well, the above is just a joke, let’s discuss the question in a serious way.
Who should we resurrect? Or who would be a greater contributor to humanity to resurrect?
If you believe that history is made by heroic figures, then great men like Shakespeare and Einstein could start a revolution in literature or physics with their great genius.
Then the question becomes: Given you a chance to choose whether to make a great advance in literature or physics.
For me, I would choose to resurrect Einstein to make significant advances in physics.
If you think that the times make heroes, not heroes make the time. Then Shakespeare and Einstein are certainly brilliant, but away from the times they live in, they may not be able to achieve so much. Then after the resurrection of Shakespeare and Einstein, although still top talent, they are likely to be unable to lead a new round of revolution.
In this situation, no matter who is resurrected, there is not much difference to humanity.
I prefer that the times make heroes.
From Homer’s epics to Hamlet, from the Renaissance to the Enlightenment, each era has its own art. It is unlikely that reviving Shakespeare will make theater flourish again.
The development of science is a process of continuous accumulation that suddenly explodes at a certain critical point. In a time of great scientific explosion, normal scientists can make great successes, and top-level scientists can make historic achievements. Today we are not in that era of the tech explosion, and the next tech explosion still needs to be accumulated slowly by people now.
The jewel of physics now is the grand unified theory that can explain the four fundamental forces: strong force, weak force, electromagnetic force, and gravity. In fact, Einstein has been working on this in his later years, hoping to unify the four fundamental forces based on the theory of relativity, but in fact, there has been no progress. Instead, he worked in the direction of quantum mechanics to unify at least three other fundamental forces except for gravity, leaving relativity to firmly occupy the territory of gravity. The probability of Einstein’s resurrection to achieve epoch-making results again is slim.
So, which one do you really want to resurrect?
