The founder of the social network said that serious concern and regulating artificial intelligence are needed to protect the future of the human race before artificial intelligence becomes a mass phenomenon.
Zuckerberg and Musk, who is chief executive of electric auto maker Tesla Inc and rocket company SpaceX, have been waging a debate at a distance over the past few days on the dangers of artificial intelligence.
Facebook is among the Silicon Valley's largest investors in artificial intelligence.
On Sunday, Zuckerberg was dismissive of such warnings.
"People who are naysayers and try to drum up these doomsday scenarios, I just, I don't understand it", Zuckerberg said in the video.
Musk even pointed out the issue of AI in the meeting probably to raise a "fundamental risk to the existence of civilization".
If I'm taking the idea of this serious-and, honestly, I think a car-centric tunnel of the future has far less of a chance of becoming reality than a "verbally-approved by the government" Hyperloop-I suppose it at least looks efficient.

Montella is trying to build something great at the San Siro, and the Portugal global can help him achieve his goals. "The idea is to play as much as I can, win as many titles as I can".
"They said on the subject (artificial intelligence - 24) with mark".
Musk, not the one to sit down quietly shot back on Twitter: "I've talked to Mark about this", he wrote.
Musk has bold ideas and the difference between him and, well a insane person is that he has a unique ability to turn those lofty, futuristic ideas into reality.
"I'm just much more optimistic on this, in general, than probably a lot of folks are".
Musk, however, said that Zuckerberg's understanding of AI is "limited".
Previously, Zuckerberg was asked about Musk's views on the dangers of robots.
A year ago a $200 million Amos-6 satellite belonging to Facebook was blown up when a SpaceX rocket carrying it exploded on the launchpad in Florida.
