General partner at Benchmark Capital for over two decades; was the lead analyst on Amazon's IPO before moving into venture capital. Writes Above the Crowd on tech and marketplace economics.
I'm not of fan of regulation for two reasons - 1) its hard to get right, and 2) its highly susceptible to regulatory capture. That said, if we insist on doing it, we should try to get it correct. As "safety" seems is the primary goal of this AI regulation exercise, I wanted to share that I recently went deep on both the 737 Max (2 crashes) and Fukushima accidents. In both cases, the investigations led to a conclusion that "regulatory capture" was the EXACT failure that led to both safety incidents. Boeing/FAA and Tepco/NISA. As a result, with safety as the #1 goal, the regulator MUST BE someo… Related

Co-founder and partner at Union Square Ventures in New York. Has written the AVC blog almost every day since 2003, on venture capital, startups, music and crypto.
I took a walk around the Union Square neighborhood a couple of Fridays ago with our new partner @mignano and we recorded it so everyone can listen to our conversation. We talked about the past, present, and future of startups, VC, and NYC. Quoting @mignano Fred Wilson is one of the greatest VCs of all time. He is also my new partner at @USV and I'm lucky to say that. We've known each other for years, but becoming partners felt like a reason to get to know him even better. So a few weeks ago, we walked around Union Square and caught up about what @fre… startups Related

Researcher on distributed systems and local-first software at the University of Cambridge; wrote Designing Data-Intensive Applications.
Their words
for me, reliability means fault tolerance primarily. So, meaning that a system should, on the whole, continue working even if like a network link is interrupted or a node crashes or something like that.

Their words
Even if we assume all three of these crashes were Waymo’s fault, that would still mean that a large majority of the 38 serious crashes were not Waymo’s fault.

A korrent is a belief a person has stated in their own words: one
sentence stating the claim, backed by a quote and a source, kept at
korrents.com .
Under a name here, the quoted block is what they actually said.
The korrent beneath it is the claim those words support, in
korrents' wording — tap it to see the record, its source, and who
else holds it.
Nobody here wrote their own korrents. They are compiled from public
statements, and a person can change their mind, which is recorded too.

About the English under a post
Some people here publish in a language other than English. Where they
do, this site shows a machine translation beneath the post, in
this typeface — the site's own, not theirs.
The post itself is never changed, moved or hidden: what is set in the
serif above is exactly what the person published, and it is what to
quote them on. A translation can be wrong in ways that matter,
especially about tone.
Only the post's own words are translated. A quoted post, a linked
article and a belief on korrents.com
are left in their original language.
