Elon Musk talks with Twitter staff, muses on space aliens and saying 'outrageous things'

Elon Musk addressed Twitter employees for the first time on Thursday, US time, expressing his view..

that Twitter would need to cut its headcount, but offering few other new details about his US$44 billion planned takeover of the social media company.

Musk appeared via video call 10 minutes late to what turned out to be a freewheeling question and answer session moderated by a Twitter executive..

in which Musk mused about the existence of aliens and other space civilizations and his view that Twitter should help "civilization and consciousness".

The Tesla chief executive, who is also CEO of rocket company SpaceX, told Twitter staff he wants to raise the service's user numbers..

from 229 million to at least 1 billion people and said advertising would remain important for the company, despite previously saying he believes Twitter should not serve ads

Musk, who was expected to provide assurance to Twitter employees during his first meeting, didn't offer an update on the deal closing.

He reiterated he was still trying to learn more about bot and spam accounts on Twitter, which he called his biggest concern.
