Wednesday’s Congressional hearing with the heads of Amazon, Apple, Facebook and Google was historic for more than one reason.  It was the first time CEOs from all the major tech companies testified at a single hearing, and it probably wouldn’t have happened that way if it were not for the new-founded procedure of

letting people testify remotely. Getting even one of those men to fly across the country for a hearing is a herculean task even for Congress. Being able to schedule them all at the same time would be close to impossible. Even a private jet is slow compared with videoconferencing.
