Tim Cook says he knows who's sending out Trump's 3AM tweets

UPDATED (4:00 p.m. ET) to include a few more quotes from Cook

President Donald Trump's tweets are finding their way into everything nowadays ... even Tim Cook's commencement speech at MIT.

The Apple CEO took a swipe at Trump's infamous Twitter habits Friday, just a few hours after the president's latest rant about former FBI director James Comey. Cook's joke at the president came while he was referencing MIT's tradition of jokes and hacks (like putting a propellor beanie on top of the Great Dome).

Another great prank he says they've pulled off?

"I'll never figure out how [MIT students] ... have obviously taken over the president's Twitter account," Cook says.

Met with laughter, he continued, "I can tell college students are behind it, because most of the tweets happen at 3 a.m."

The jab wasn't lost on some Twitter users, either. And they loved it.

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."

He also took a moment to mix a bit of helping humanity with a touch of self-promotion, noting how Apple products have been good for society.

The internet is a tough place, sure. Just keep up those prank tweets, though, kids.
