How did WeWork founder's car ride with Masayoshi Son lead to its $47-billion collapse?

WeWork Co-founder Adam Neumann said a 2016 car ride with SoftBank CEO Masayoshi Son, which ended with a $4.2-billion investment offer, set the $47-billion company on a path to collapse. Neumann said his ego became inflated, adding, "I forgot what we were all about...It suddenly became about the money." "And when I lost it, everybody lost it," he added.
