Chris' note: Last night, 25,997 of your fellow readers tuned in to watch Silicon Valley insider Jeff Brown's Beyond Exponential summit. It's easy to see why it was so popular… Jeff has handed readers the chance to close out gains of 221%, 239%, and even 332% from stocks that harness the power of exponential growth. And after crisscrossing the U.S. during the pandemic, he revealed for the first time his No. 1 way to profit from exponential tech over the next decade. Then read on below to hear from Jeff on why one of the best hunting grounds for exponential growth plays is artificial intelligence (AI). In the summer of 1956, John McCarthy was a young assistant professor of mathematics at Dartmouth College. He met with other scientists to discuss a topic that most people considered science fiction… thinking machines.

"Most professional scientists aim to be the first to publish their findings, because it is through dissemination that the work realises its value." So wrote mathematician James Ellis in 1987. By contrast, he went on, "the fullest value of cryptography is realised by minimising the information available to potential adversaries." Ellis, like Alan Turing, and so many of the driving forces in the development of computers and the Internet, worked in government signals intelligence, or SIGINT. Today, this covers COMINT (harvested from communications such as phone calls) and ELINT (from electronic emissions, such as radar and other electromagnetic radiation).

He was given extensive access to the secret files of the intelligence agency, although some limits were placed on what he could see and write about, including more recent interceptions of other country's diplomatic messages and some of the technical secrets of code-breaking.
