As one of the most successful tech growth stories of the 2010s, obviously they 1,000X'd the returns of the S&P over that time.

The real question is though, going forward, what ROI will Airbnb deliver vs. the S&P 500.

Growth stocks seem to be nearing bubble territory at the moment, so if we get a repeat of the 2000s where interest rates start rising again and value stocks become more in favor, it doesn't look great.

Then again, selling fractionalized access to highly restricted real estate supply in all of the world's major cities doesn't sound like a bad bet for the future. If the lack of desire to invest in new construction in cities due to the covid narrative of cities being dead (obviously overblown) leads to further supply deficits, the future for Airbnb looks bright.

So in summation, its impossible to predict, buy index funds instead.

That's one data point.

Let's look at the data in aggregate instead, in order to make a decision, using the link I already gave. It's an extraordinarily low risk.

Here's how I interpret Gödel's landmark result:

> semantic properties, except for the most trivial systems, can't be inferred from syntactic properties.

E.g. you can't type a program by seeing everything is using the correct literals and syntactic objects: you need to, sooner or later, know what the program /actually does/.

But the problem is that mathematicians do, in fact, reason about semantics. So saying that "it's uncomputable" ignores the elephant in the room, which is that mathematicians compute theorems for a living. What do mathematicians have that enables them to compute the uncomputable: well-aligned chakras, magic, coffee grounds, the zodiac, etc...?

I'd love figures on how many PhDs are issued broken down by school in timeseries format. JDs don't count. Would be helpful to know who is debasing the currency. Caltech definitely isn't. One of the few actually elite institutions left. No fake subjects either.

I'm guessing places like Harvard, UCB and MIT each issued close to 1000 last year. Lower ranked schools, maybe 500 each; probably cumsum to significantly higher than CalTech even with short histories.
While true, I can't edit my kidneys/liver/body yet, so for now I need to edit diet.

I have always been fully vaccinated. My children have been fully vaccinated. But I have to admit some trepidation about a fast-tracked vaccine.

> Capital One used to offer different mortgage rates to IE users and Firefox users;

This was driven by looking at the User-Agent header your browser sends on every request, not sniffing your local network connection.

Similarly, the Verizon super-cookie header wouldn't affect HTTPS traffic (this was one of the motivations behind HTTPS-everywhere campaigns since even many people who think the NSA can track them no matter what mind marketers doing it) and the point was tracking individual people across multiple devices, not simply gross device fingerprinting. Even if your VPN connection has 100% uptime they can do the traffic analysis I mentioned but since it's almost certain that there will be some non-VPN requests they would already know that you have at least one Apple device.

The underlying issue here is that the kinds of things you're worried about happen in the browser. Using a VPN adds reliability and performance issues but it doesn't prevent this kind of basic identification and very, very few people aren't going to leave some kind of far more identifying cross-site activity which would uniquely identify them rather than just narrowing it down to one of the most popular consumer brands.

One way I have seen is to have a cadre of scientific/medical advisors with skin in the game (usually, on the board). This is also one of the paths out of debt for MDs that don't want to practice or MD/PhDs in general. With a few people that actually know the science/art, you can then focus on the finance and other issues.

The science part isn't always hardcore mol-bio, as many devices can be a bit more like traditional engineering (even internal ones). But many of the problems that the various agencies will cite will be mol-bio related. Even as a hardcore investor, unless you have the many years of background, or can get people with background to put their own money in it, you are going to have a hard time. Paying just for consulting isn't likely to be appropriate due-diligence. Biology is monstrously complex and frustrating even in one individual, let alone a population. As such, it takes a lot of research to have a good clue of what is going on, more so that you can likely pay consultants for.

EDIT: Again, I want to stress that every situation is different and that I am only relating my personal experiences here.
Argh... this is the nuance I was talking about in another post. Godel's Completeness Theorem (which applies to many systems that Godel's Incompleteness Theorem also applies to) shows that in a sense semantic properties coincide with syntactic properties and so in fact can exactly be inferred from syntactic properties.

What instead Godel's Incompleteness Theorems show is that you cannot exhaustively list all the semantic properties of what you care about, but combined with Godel's Completeness Theorems, only the ones "relevant" to your syntactic axioms.
Very off-topic, but long ago when Albert Einstein went for a car ride with Mr. Gödel to become U.S. citizens, Einstein was trying very hard to think of ways to shut him up about a Constitution loophole he discovered. Things didn't go exactly as planned, and in front of the naturalization examiner, Mr. Gödel started blabbing about how he had found a way the U.S could be transformed into a fascist regime...

There are many reports of high compliance. E.g.
https://www.politico.eu/article/sweden-coronavirus-lessons/
"93 percent of the population say they are following social-distancing recommendations." Maybe compliance has waned since. I don't know.

Here's a typical narrative that illustrates why we should be more careful about the word "lockdown":

Alex: "Sweden has successfully managed COVID19 without a lockdown."

Bob: "Great, so we should just go and live our normal lives then."

Alex: "Actually no. We need to cut off most social contact, ban visitors to rest homes, and work from home when possible."

Bob: "Er, that sounds like a lockdown to me!"

Alex: "WELL ACTUALLY it's not a lockdown as long as the government doesn't assert the legal authority to enforce these restrictions."

Bob: "... but the effects on health, well-being and the economy will be the same as a lockdown?"

Alex: "If everyone complies, which we expect them to, then yes, but the important thing is that we don't call it a lockdown."

As a person who lives in Sweden, here is my best guess. While we did not have mandated lockdowns, there was relatively effective, voluntary limitation of indoor social gatherings throughout the summer, which limited the spread of covid19. Sure, businesses mostly stayed open, but Swedes tend to try to avoid each other to begin with. Asking some Swedes to stand 2m apart in a store would be asking them to stand closer together than they would prefer.

Swedes spend a lot of time outdoors, especially in the summer. (Not suggesting more than elsewhere; most places seemed to have better numbers in the summer.) Now that the weather is turning less pleasant, more people spend more time indoors. Therefore, transmission is rising again.

> Sweden should have enjoyed a flat and sustainable level of infections.

So I think therefore that this didn't really happen, which means now we get our second wave. In some places, such as the nearby town of a few thousand, we are actually only starting to get a first wave as we never really had a first wave yet.

Still almost no mask wearing, though. Not sure when or if masks will happen here, although I have seen packs of them at the market now.

Again, I am no expert and I have not looked at actual transmission numbers throughout the summer etc. This is just my best guess.

Edit: What I mean is, I don't think most regions of Sweden had sustained levels of transmission during the summer, in case that wasn't clear.
>But a new kind of "hotel" that consists of one person running a handful to a couple dozen apartments.

The most important part of Airbnb is creating a hotel "chain" or "brand" without having to deal with things like zoning or licensing or insurance for hotels.

While Hilton/Marriott/IHG/Hyatt/Accor/Choice/Wyndham/etc collect 10% to 20% in exchange for putting their brand on the line, Airbnb also was able to create a business where they can take 18% without putting their brand on the line, and keeping the ability to dump all the liability on the hosts. However, I think this is a weakness for Airbnb long term, but they may be able to take advantage in the short term.

Quality control for real world products, especially volatile ones such as abodes rented night after night, are costly and I'm willing to pay a premium to make sure there are some double or triple checks going on.
> Why is Sweden seeing a second wave as well? Why did the number of infections soar, while it should theoretically have remained constant?

I think we can now conclude that covid19 behaves seasonally, just like other respiratory viruses.

But nobody knows exactly why. There are many theories, but none universally accepted: Summertime higher vitamin D levels from sunlight, maybe this gives better immune defense. Sunlight disinfects surfaces. Colder air is dry, respiratory droplets stay afloat longer and spread better in dry air. People's mucous membranes stay healthier in more humid air, maybe they are more susceptible for virus attacks in dry air. Maybe the patterns of how much people meet each other indoors is different in cold weather.

What Gödel did prove was that the above list of statements (and infinitely more) must exist.

The special thing about his proof is indeed that it is recursive, i.e. adding another axiom can't fix the problem. But that was only necessary to prove that no formal system can be perfect, ever.

Most undecidable problems can indeed be "fixed" by adding another axiom, but if you go beyond the ones of ZFC it becomes less clear which of the two alternatives is the "right" one...
Just to set some context, I'm of the "OOP Generation" where I learned to program when OOP was at its zenith. Every major language was Class-based OOP (C++, C#, Java, Python, Ruby) and it was just THE way to code for all things in the foreseeable future.

That said, I've since looked into and learned other methods of programming: classic C, prototype-based JS, functional Clojure, and Go.

From what I can gather, even from the SOLID principles and other Class-based OOP advice (prefer composition over inheritence) is that Interfaces (as abstraction and reuse), Aggregation (that objects can have other objects), and Delegation (which allows of ergonomic aggregation) are the real winners of OOP.

In this way, Go gets it mostly right IMO, though at the risk of "initial hype" I'm still cautious on it.

It feels so backward that OOP is taught with a focus on abstract & subclasses, with very little emphasis on interfaces, which is really how we achieve the goals of abstraction and reuse.

What's funny is seeing languages like Java trying to "undo" the arguable "mistake" of abstract classes by adding more and more power into interfaces: default methods, etc.

To your original conversation, there's a mix going on with "model." Are they talking about the Service's API Model, the internal model representation, or the database model? The outer layers (API & Database) of your code should be plain structs (POJOs in Java), but you're absolutely right that within the business code itself, you should have logic within the classes. Otherwise, you're not coding much different than C passing around struct pointers.

This is not how the Prisoner's dilemma works since not getting the vaccine is not a purely dominant strategy. You are neglecting to adjust the vaccination scenario payout to account for the fact that you personally are much less likely to get Covid-19 if exposed to someone infected. This benefit largely exceeds any cost of receiving the vaccine based on current data.
