Back-to-back rocket launches, multi-billion dollar acquisitions and a car that drives itself bring a lot of futuristic and daring images to mind, but one word that may not immediately come to your tongue when you hear all of these things is “cautious.” According to IBM’s supercomputer, cautious is exactly what Elon Musk is.

As first reported by CNBC, job search firm Paysa used IBM’s supercomputer (and brilliant Jeopardy contestant) Watson to determine the top 11 most cautious tech leaders in the nation.

The scoring was on a scale from 0, being least cautious, to 1.0 as most cautious. The scores were calculated from speeches, essays, books, interviews and a variety of other communications. After gathering more than 2,500 words of these industry leaders, Paysa ran the data through the Watson Personality Insights API.

“Personality Insights extracts personality characteristics based on how a person writes,” according to IBM Watson’s website. “You can use the service to match individuals to other individuals, opportunities, and products, or tailor their experience with personalized messaging and recommendations. Characteristics include the Big 5 Personality Traits, Values, and Needs.”

Musk, the man behind some of Silicon Valley’s most prolific companies, scored the highest of all tech leaders in the country, getting a .96, with Cisco CEO Chuck Robbins nipping at his heels with .95. Other men that have a foothold in the autonomous vehicle industry, Apple’s Tim Cook and Alphabet’s Larry Page, also appeared on the list. Cook came in at 8th with a score of .85 while Page got .73, tying Facebook’s Mark Zuckerberg for the least cautious leader in the tech space.

The successful CEO has recently made headlines for getting involved in an array of businesses ranging from music streaming to underground tunnels, businesses with high risk that could yield high reward. The supercomputer deems most of Musk’s ventures to be calculated risks, which are technically cautious and a vital part of company growth.
