Musk retweeted a post from @teslaownersSV, which quoted Carmack's comments praising Musk's "all in" spirit at SpaceX and Tesla. The comments noted that Musk, instead of retiring to enjoy his wealth, chose to take enormous risks and fully dedicate himself to "world-class endeavors" such as "space, cars, and energy," even risking bankruptcy. This spirit, the comments concluded, deserves more respect.
