Trump wasn't the only subject of Cook's address though. The Apple CEO also talked about the importance of technology, but made reference to its downsides.

"But technology alone isn't the solution," he said. "And sometimes, it's even part of the problem."

Cook also recalled a conversation he and Pope Francis had about technology, in which the Pope expressed concern over the way humanity's never had so much power over itself — but nothing ensures that tech will be used wisely.

Cook said most of the time, technology is a force for good, but said there are adverse consequences stemming from it, such as threats to security, privacy threats, fake news and social media "that becomes anti social."

"Sometimes the very technology that is meant to connect us, divides us." he said.

He warned against becoming too hung up on social media—and seemed to take a bit of a shot at Facebook—saying the best way to measure your impact was "not in 'likes,' but in the lives you touch."
