Mark Zuckerberg testifying in congress reminds me of the Star Trek movie First Contact when Data was starting to feel anxious around the Borg, so he disabled his emotion chip.
Honestly though he handled that extremely well and made it backfire.
Congressional hearings are purely for political grandstanding. The low height seat countered with a cushion, the dumb questions answered with direct unemotional answers. 'we sell ads senator'. The entire process had nothing come out of it except a few politicians had egg on their face.
