Mr. Trump, Do You Realize How Much the World Has Changed Since You Were President?

Donald Trump left the White House nearly four years ago. Given his self-confidence, I suspect he is now thinking: “What could be so different? I’ve got this.”

Well, I just traveled from a reporting trip in Tel Aviv to a conference in the United Arab Emirates to a deep dive with Google’s DeepMind artificial intelligence team in London, and I think the president-elect would be wise to remember a famous aphorism: There are decades where nothing happens, and there are weeks when decades happen.

What I saw and heard exposed me to three giant, shifting tectonic plates that will have profound implications for the new administration.
