Science

Your son or daughter will need to encourage that interest.

My youngest son designs nuclear reactors, but he's relatively slow as he's in his twenties, not his pre-teens like your grandson.

My oldest son always builds his own computers but he started doing that in his 20s

I am told that 70% of Chinese government officials have engineering or scientific degrees.

This is why they will dominate the future.

I suggest that your grandson take some time and space from that fine mind of his and do what my son did, learn to speak and read Chinese.

Really, our country will need people like your grandson. Nuture him, encourage him.

When my youngest was a star in high school, I took him on a bike ride, and took a break, and we stopped to rest on a bench to explain to him that his mind did not entirely belong to him. I told him he owed it to humanity, that it was a responsibility not a privilege. I don't know that he was humoring me, but he told me he understood. I told him the greatest ethical shortfall of my life was not understanding as much when I was young.

I do want him to get out of the country until it is ready for rebuilding after this festival of ignorance is over.

Good luck to your grandson. You should be proud.
