If all day long Zoom calls and Slack messages could have led to spontaneous discussions/new initiatives like that they already would have, but they didn't, I saw more sparks flying in one afternoon of social event than 3 months of planned video calls.
I firmly believe if Silicon Valley goes fully remote, then it will no longer stay the innovation engine of the entire tech industry. Startups in China will eat us alive. You simply can't replicate the energy of Haidian District or Shenzhen with group messages.
