Musk spoke to employees of the social network for the first time since announcing plans to buy it.
Musk deviated from the discussion of potential layoffs to an entirely unforeseen topic: aliens.
According to CNBC's report on the closed-door meeting, Musk talked about human consciousness and how he had yet to see any evidence of aliens.
According to Insider, he asked if we could travel to other star systems and see if there were alien civilizations.
It is possible that Musk did not read the room, with a restructuring that could be frightening to current employees. The billionaire CEO didn't rule out the possibility of layoffs if they keep spending more than they make.
Musk said that he'll allow users to say pretty outrageous things within the law, but that they shouldn't amplify them.
He wants to charge users to verify their identities.
The topic of aliens and human consciousness are well trodden talking points for Musk, but was this the right time to bring them up, with tensions high and thousands of livelihoods on the line?
It showed that the number one rule of Musk is to expect the unexpected.
During a meeting with employees of his company, Musk told them he hadn't seen any evidence that aliens are real.
