Musk muses about Mars and Earth – but stays quiet on Twitter deal

Billionaire avoids talking of collapse of $44bn deal but talks about colonizing Mars and boosting Earth's birthrates at conference

Elon Musk reportedly talked about the colonization of Mars and boosting Earth's birthrates during his keynote address at Allen & Co's Sun Valley conference on Saturday, but he avoided discussing his attempt to withdraw from his $44bn bid to buy Twitter.

Musk's talk to close out this year's edition of the Idaho conference which annually draws tech, media and finance gurus became one of the hottest tickets after lawyers for the Tesla boss filed notice Friday that he was terminating his bid to acquire Twitter. The billionaire accused the social media firm of failing to provide information on bot accounts, among other things, making observers wonder whether he would address such complaints at his speech scheduled for the next day.
