On June 13, legendary venture capitalist Marc Andreessen told angel investor Sriram Krishnan about his now-famous essay, "It's Time to Build," for Krishnan's newsletter, The Observer Effect. Andreessen said he wrote the entire essay, which calls on entrepreneurs to use the pandemic and related shutdowns to reinvent and rebuild malfunctioning parts of society, in a single evening. He felt compelled to write the post after reading an article about the widespread shortages of personal protective equipment in the nation's hospitals.
