Is a network -- whether a crowd or blockchain-based entity -- going to replace the firm anytime soon? Not yet, argue Andrew McAfee and Erik Brynjolfsson in the new book Machine, Platform, Crowd. But that title is a bit misleading, because the real questions most companies and people wrestle with are more "machine vs. mind", "platform vs. product", and "crowd vs. core". They're really a set of dichotomies. Yet the most successful systems are rarely all one or all the other. So how then do companies make choices, tradeoffs in designing products between humans and machines, whether it's sales people vs. chatbots, or doctors vs. AIs? How can companies combine the fundamental building blocks of businesses -- such as network effects, platforms, crowds, and more -- in a way that lets them get ahead on the chessboard against the Red Queen? And then finally, at a macro level, how do we plan for the future without falling for the "fatal conceit" (which has now, arguably flipped from radical centralization to radical decentralization) ... and just run a ton of experiments to get there? We (Frank Chen and Sonal Chokshi) discuss all this and more with Brynjolfsson and McAfee, who also founded MIT's Initiative on the Global Economy -- and previously wrote the popular The Second Machine Age and Race Against the Machine. Maybe there's a better way to stay ahead without having to run faster and faster just to stay in place like Alice in a tech Wonderland.

"We're always fighting the last war" -- that's a phrase historians like to use because policymakers and others tend to be so focused on the threats they already know, and our mindsets and organizational structures are oriented to respond that way as well. And in the "situation room" of nation states (including the intelligence briefing war rooms in the White House), much of the security conversation is necessarily focused on the worst possible scenarios, broader context, and attribution as well. Companies, however, unlike nation states, do not have to worry so much about attribution (who did this? why) or even as much about the sexy, headline-grabbing threats. In fact, they may be better off focusing on security hygiene and basic metrics for assessing risk in the boardroom -- much like they review financials regularly -- argue the guests in this hallway-style conversation episode of the a16z Podcast. Herb Lin, who is Senior Research Scholar for Cyber Policy and Security at the Center for International Security and Cooperation and is also at the Hoover Institution, both at Stanford University; David Damato, Chief Security Officer at Tanium; and a16z policy team partner Matt Spence (who among other things previously spent time at the White House working with the National Security Council) begin by sharing their views on the term "cybersecurity" ...and end up with practical advice for a security boardroom 101. No matter what, security should have a seat at the table.
