VERIFY IDENTITY

“To solve the proof of human problem, you will need to distinguish one new individual from all previous individuals. You need to make sure that Ben is trying to sign up, and Ben did not sign up before. Then you can just do the math, and you can calculate how much mathematical entropy do you need to prove that? It turns out that's a pretty high number.”

“We changed it, actually, it was KIND because we believed very strongly, not only in well-functioning communities, but in collaborative communities that support each other. But ultimately, in today's world, when you put something like that out there, it's more a reason or becomes a reason for people to attack you versus something to stand for. And so we changed our ticker to NXDR in a way because we said, look, the ticker is not the representation of Nextdoor.”

“Proof of Human, as the name suggests, is do you know if you interact with a human or something else on the Internet? And I actually think the kinds of questions that we're now asking is, are you interacting with a human, an agent on behalf of a human, or just an agent? I think these are roughly the three areas that we want to split apart.”

“a small group of us, five people, we had a dinner together in Palo Alto and we talked about, gosh, if we started a company, what would it be like? We weren't even going to start a company together, but each of us individually were dreaming about being founders. And it was so powerful to have that mini community of people that wanted to do the same thing. You didn't feel alone... And we called it Round Zero because it was prior to Round One Financing”

“We went down, if you know World, you know that we have built this thing called an orb. It's doing a lot of things to prevent these kinds of attacks. For example, it has multiple sensors in the electromagnetic spectrum to just make sure that you cannot show a display to it and it would recognize that.”

“An AI will be able to have a GitHub account, and will be able to post and own an account, and also attest to five other AIs that these are in fact humans, even though they're not. We disregarded Web of Trust basically immediately because we assumed that eventually everything that is just digital and AI will be able to do as well.”

“we moved to Dallas, Texas, which is where my parents are, where my only sibling is with his family. And I grew up in Texas. You know, I mentioned Odessa, Texas. This is where I grew up. When we moved here and we moved into a neighborhood, we had multiple neighbors drop off fresh baked cookies on our front door. Now, it's the middle of the country. It's a suburb. It's not this amazing mecca of innovation and metropolis known as San Francisco, right?”

“the second thing is the internet has memory. And so if you go to one of these subreddits, for example, and you're engaging in the conversation and you say things, those things that you say, which are then created as bits on the page, that may last for decades. Whereas when you're just SMSing with a friend of yours, telling jokes or a family member, talking about things that don't really matter, that just goes off in the ether and is forgotten”

“Data is a great support system for decision making, but data should not be the thing that's driving the decision itself. And it's one of the things, particularly in our industry, as quantitative as we are, I think data is extremely powerful and I would never make a decision without looking at the data, but I wouldn't just look at the data. I would need to interpret it.”

“I have a very good friend, Jim Lanzone, who's now the CEO of Yahoo! He came over to visit me one day and on his way into the office, his wife called him and they had a conversation and he mentioned that he was visiting me. And his wife set me up with the woman who is now my wife. And that all happened prior to Jim coming into the office. And it never would have happened if he wouldn't have come to that office because as he was talking to his wife, his wife said, what are you doing? Where are you?”

“as I often tell people, if folks know who you are, you have a reputation to protect. And if you have a reputation to protect, you will act a certain way versus if you feel like no one knows who you are and your reputation can't be harmed by what you do, people will act very differently.”

“I found that in many cases success is not the right environment for innovation, because success is something people want to hold on to, whereas failure and struggle is when you have that expression, necessity is the best form of invention or whatever the expression is, right? If you're struggling, you have to make changes. If everything's working fine, you kind of take your hands off the wheel and say, why would I want to mess anything up, right? But then before you know it, that creative destruction happens”

“I do believe that COVID was something that was not organically created from a wet market in Wuhan... At the end of February, we were skiing in northern Italy in the Dolomites and with our three sons. And we came back to Florence where we were living. And we noticed that there were Asian tourists that were wearing masks. And that was really striking to us because we were not familiar at all with anyone wearing a mask. And then obviously, days later, we realized that there had been this outbreak in Wuhan.”

“What is so hard about this problem is it's going to be a global problem. And so it doesn't really matter if one government maybe has the perfect infrastructure. Singapore is an example of a government that has perfect infrastructure, but that barely matters because Meta is a global product with three billion users and a lot of other countries.”
