Microsoft co-founder and philanthropist Bill Gates stopped by The Washington Post on Wednesday and sat down for an interview with The Fold. During the interview, which mostly centered around introducing new, better ways of testing teachers, Gates addressed the increasingly dire threat of a major cyber attack.

“The cyber thing — it’s wonderful that more attention is going into that,” Gates said. “Whenever you get a critical infrastructure system like the electricity system in the U.S. you’ve got to really look at what resiliency that system has. And the cyberworld today has a lot more investment to make to have the right resiliency.”

Watch the full interview, and check out The Fold at 6 p.m. ET weekdays.
