All right! Good morning, everybody. This is Preston Pysh. And I’m accompanied by my co-host, Stig Brodersen. And we have brought Hari Ramachandra back on the show because we are talking about something very interesting today: Google. For everybody out there, I’m sure they have used Google with their search results.

But picking apart and understanding what it is that makes Google tick is something that very few people understand. And so, today in our show, we’re going to be talking about a book that all three of us have read. And the name of the book is, In the Plex. This is a best-selling book, and this is by Steven Levy. And the subtitle of the book is that it talks about what Google thinks, works, and shapes our lives. And so that’s what we’re going to be discussing today as we kind of go through the essence of this book.

So for today’s show, we are going to break this down into two different segments. The first segment, we’re gonna discuss the book and we’re gonna be really discussing what it is that makes Google tick. At the end of the show, we move into the second segment, and we’re going to be talking about our thoughts on why or why not we would own stock in Google. So we’ll go around the horn and get everybody’s opinion. So let’s go ahead and kick this off.

We’ll start off with the very first point. When this book opens up, and I found it just absolutely fascinating the way that this book starts because the author talks about what it is that Sergey Brin and Larry Page, who are the two founders of Google, what their overall mission and goal is for Google. And that mission is that they want Google to be the brain of the world. And I think for a lot of people, they hear that and they’re like, “Okay, so what in the world does that mean?” And it’s, it means exactly what I said, is they’re trying to take Google to be the hub or the brain of every thought that’s ever been captured in the world; that’s been captured on the internet and harnessing that, and, and providing that to people.

So if you ever have any question whatsoever, that question can be immediately answered with your smartphone or your computer by just typing in whatever your question is. That’s their goal. They want there to be no boundaries between language. So if you type something in and you want to know what that means in Korean, or Russian, or any language, you will get the answer no matter what. So that’s a pretty lofty goal. That’s something that I think a lot of people might think, “Wow, I didn’t really necessarily realize that that’s what they were trying to do with their little one-page entry point for the search, where you just type one thing in, and it pops up.” But that’s really what they’re trying to do, is they’re trying to harness every thought that’s ever been captured in the world and making that accessible.

So let’s talk about how computers work and how Google works in general. So whenever you think about data, and that’s what this is, is it’s stored data. You’ve got to realize that every piece of information; when you type something down on your keyboard, and you save that information on, let’s just say a word document; that is a file, and that file sits on your computer. And so, what the World Wide Web does is it, it links all these different computers together, so that I can have access to maybe say something that Stig wrote over in Denmark. Or let’s say, Hari wrote something over in San Francisco and captured it on a Word document. Through the internet, I am able to link to that file. And what a lot of people don’t realize is that the internet works a lot like our mail system; our, our old-fashioned type up a letter, put it in the mailbox, and send it off.

So let’s say that Hari types up a Word document, and he stores it on his computer in San Francisco, and I want to have access to that file through Dropbox, or he puts it on a web page, or web server, or whatever, and I want to access that. So whenever he saves that document, it’s saved on his computer at a particular IP address. And I’m sure a lot of people have heard IP address before, okay? And what an IP address is, is it’s no different than your physical address. So I have an address if somebody wants to send me a, a piece of mail or a box through the post office. And so, that IP address is exactly like that mailing address. And so, if I want to go get this file off of Hari’s computer; if I know his IP address, I could access that particular file by going to his computer. And that’s how all this is linked together. And so what Google does, and let’s get back to the–our discussion on Google. What Google has done is it has mapped the entire world’s computers, where all this information is saved, okay? And they’ve mapped it; they’ve indexed it, so that they have this all saved on computers that they’ve had. It’s basically like a backup; a copy of everything that’s out there. And so they have these massive web servers.

They have these massive supercomputers in these data centers around the world. And these computers are constantly looking at everything that is called, “crawling the web.” They’re crawling the web for all this information, and then they’re making duplicate copies of this information on their computers, in order to know what’s out there; in order to provide you the best search results. So how did Google really become and rise to the top as being one of the top search results, in order to find this information because if you think about that problem of trying to point somebody to the, to the information that you’re seeking, that’s a really hard and complex problem is. Everybody’s typing up all this different information all over the world.

So how do you point them to the, to the article that they’re actually searching for? And how do you get it right almost every single time? And so how the founders of Google which is Larry Page and Sergey Brin did this is they thought about the problem from a different vantage point. Whenever search engines first came out, it, they were based off of keyword density. So if, let’s say, I was looking for an article on tennis, okay? If the article had the word tennis in it 5000 times, that search result would would rise to the top and that would be the article that would be, you know, showed as the best result. Well, as many people caught on to this, they would hide the text in the document through the HTML, and they would just type tennis about 5 billion times and then their article would naturally rise to the top.

So that didn’t work real well because you had really kind of bad content that was search engine optimized. And that’s how it rose to the top. And so what the founders of Google did is they did it a little differently. And they said, “Let’s treat this like it’s a research paper.” And whenever you write a research paper in academia, which both of these students were out at Stanford University and working on their doctorate, whenever they founded Google; when they started off with a thing called Page Rank, which was what Larry Page had called his first search engine. The way that they framed it is they said, “You know, whenever you find a really good research paper, at the bottom of that research paper, it has all these work cited references to other documents; to other, you know, professionals that have written about this.”

And so they said, “Well, if everybody’s constantly linking or showing that the…maybe this article by this professor over in Harvard wrote the best article on tennis, let’s go back to that example. If everybody’s referencing this one document, that document that’s being referenced is probably the best result and shows the most authority. And so they took this idea of referencing at the bottom of the page to a different level, and they started treating that as the link to the other person’s content is a clue as to what is the most important piece of information to be found. So Stig, go ahead. And I see you have a comment that you want to add.

Stig Brodersen 8:35
Yeah, so what’s really important to understand is that Google wants to do its best to mimic the behavior of a real-life person. And clear–the problem is if you want to map the whole world, you can’t have a person, or hundreds, or thousand people doing that. That’s simply impossible. So what they’re doing is that they are adapting the algorithm to act the most like a human being. And one way to do that, as Preston is saying is looking at how many people are referencing; what we also call backlinking. So how many people are backlinking and saying that this page is relevant or this site is relevant for what you are searching for?

Preston Pysh 9:11
A fantastic point on how their algorithm works there, Stig. So just a little background, so whenever Larry Page and Sergey Brin founded the company at Stanford, they were just starting off, and it was really a research project that they were doing. And so, they were using the servers and the computers at Stanford, whenever they were doing it. And they started getting so much traffic coming to their site because their results were populating such good quality results, that the servers there at Stanford started getting over used, they started buying more computers, and it just kind of evolved into this massive monster of computing power. And I think that at that point, it says in the book that they kind of realized that they had something fairly huge, and so they ventured off. Hari, do you know how much–didn’t Stanford get some of the equity of Google, whenever they decided to, you know, move outside of the campus of Stanford and found their own business? I can’t remember in the book, but I thought I remember hearing like 10% or something like that.

Hari Ramachandra 10:12
You’re right, Preston. Around that number. In fact, Stanford has a very good incubator program. A lot of companies in the Silicon Valley have come out of Stanford, including companies like Sun, Yahoo, and others. And Stanford professors are known to have industry connections. And also, many of them have founded their own companies as well.
