<p>Yea that could have been worded better. My point was more that the banks didn't turn into software (an app) with just developers working on it, just that the labor force that was doing teller operations moved.</p>

<p>Two anecdotes I'll share:<p>First: Most people believe it was Netflix that killed Blockbuster, but that's not strictly correct. It was the combination of Netflix <i>and</i> Redbox that really sealed the deal for Blockbuster (and video rental generally). It normally takes not one, but at least two things to really fill the full functionality of a old paradigm. Also it's human nature to focus heavily on one thing (Blockbuster was aware of Netflix) but lose sight of getting flanked by something else.<p>Second: Not listed here is how banks themselves have changed to be almost entirely online, which in many cases is more of a outsourcing play than a labor destruction play. My favorite example of this is Capital One, where the vast majority of their credit card operations literally cannot be solved in a branch. You must call them to say, resolve a fraud dispute. Note that this still requires staffing and is (not yet) fully automated, just not branch staffing. It doesn't make sense to staff branches to do that.</p>

<p>So I've driven Route 50 between Tahoe and Placerville a few times. Many of these times the weather has been quite bad. Many of these times I've had to wait for hours while an accident was cleared, or 12 foot snow drifts were plowed.<p>When I'm traveling in mountain snow, I'm always very neurotic about prep. AWD or 4x4, water, chains, food, emergency kits, etc ... I always assume I could be stuck for 24 hours or more.<p>In the meantime, I am constantly shocked by how many people make this trek with little or no respect for how deadly snow can be. The worst of it is when it puts others in danger: I'll never forget seeing a front-wheel drive sedan repeatedly driving up, then slipping back on a steep hill, while a line of 20 cars waited behind it.<p>Part of it is just not knowing (I grew up in the east coast), but part of it is just human nature to not understand some things to be inherently dangerous. Snow and cold looks so serene, but cold in it's various forms has killed many more people than heat.</p>

<p>I'm not that old, and I still remember being really disappointed when something wasn't in my home (book) Encyclopedia. Then you would trudge to the library to find maybe one book on the obscure topic.<p>You could request a book be sent from another library, but that would take weeks, and you had no idea what was in that book.<p>It was wild. Most things were just unknown, or whatever you parents told you.</p>

<p>Was shocked to hear this news. I worked for Google years ago but I was in the NYC office, so we didn't run into the YouTube folks much.<p>Opinions about YouTube may be mixed here on HN, but it is objectively one of the most successful businesses in tech or media to emerge in the past 15 years. If it weren't buried inside Alphabet, Youtube would be worth on the order of $400 billion, more than Disney and Comcast combined. It's a weird mix of a huge creator monetization network, a music channel, an education platform, a forever-store of niche content, and a utility.<p>It's also not a business that rested on it's laurels. It's easy to forget how novel creator monetization was when YouTube adopted it. They do a lot of active work to manage their creators, and now have grown into a music and podcast platform that is challenging Apple. To top it off, YouTube TV, despite costing just as much as cable, is objectively a good product.<p>Few products have the brand, the reach, monetization, and the endurance that YouTube has had within Google. And I know for a fact that this is in no small part due to the way it was managed.<p>I've probably watched tens of thousands of hours of YouTube at this point. Some of it sublime, some of it absurd, some of it critical for my work or my degree. I couldn't imagine a world without it.<p>RIP.</p>

<p>> coal (a fuel you can run the engine on) is of course going to be very cheap and abundant directly above the mine where it is being produced and for the atmospheric engine to make sense as an investment the fuel must be very cheap indeed.<p>So effectively, once coal was discovered as a fuel where spending small amounts was well worth mining large amounts, steam engines were bootstrapped into product/market fit right on top of the use case.<p>Fun fact: Modern off-grid pump-jacks operate in a similar manner. They use the natural gas that comes from the well to power the pump that pumps the oil [1].<p>[1] <a href="https://en.wikipedia.org/wiki/Pumpjack" rel="nofollow">https://en.wikipedia.org/wiki/Pumpjack</a></p>

<p>This only would have worked if it was animated. The 1977 Hobbit film which was produced for NBC [1] was a excellent adaptation, and Yellow Submarine is in the same style.

<p>I used to use the WeWork on the bottom floor (technically partial basement). This is definitely the vibe: Huge open floor, no windows. WeWork did an OK job trying to light it but, I could never shake the feeling that it felt like a scene from Fallout.<p>My two cents: If this building ever becomes popular again, it'll be because of the location and not because of the building itself. It's reasonably close both to "Van Mission" (the rebranding of that part of Market Street for high rise residential), a BART stop, and Hayes Valley. It's probably one good Twitter-esque city tax subsidy away from being fully occupied in 5 years.</p>

<p>Amazon and Uber are definitely different, but in 2003 Amazon's market cap was about $21B, or ~$36B in today's dollars. Uber is actually bigger than that in value today (~$144.11B).<p>Amazon was far from a dominant player in 2003, and AWS wasn't launched publicly until 2006.<p>From a product standpoint, as others have stated, Uber is a real-time services marketplace vs Amazon which is more about physical goods (again, excluding AWS, which is technically a service). Most of their value is putting all the work into the ground to keep the marketplace balanced, which is a tricky marketing and econometrics problem. One need not look farther than Lyft to see how hard it is to keep the "5 minutes away or less" guarantee.<p>Also to those who think the app is a non-trivial technical achievement, I would recommend reading some of the blog posts that go into some of the crazy technical challenges they hit [1]. Specifically in some cases, in order to make the app work in all geo's, they ran up against practical limits to binary size at Apple. Not to mention that geo / waypoint data is a genuine "big-data" problem and not easily reproduced by just any company.<p>[1] <a href="https://blog.pragmaticengineer.com/uber-app-rewrite-yolo/" rel="nofollow">https://blog.pragmaticengineer.com/uber-app-rewrite-yolo/</a></p>

<p>This is correct. For the most part, you are taking the money from your profit centers to invest in new initiatives. Could be geo's, could also be verticals, etc.<p>This is not at all unusual for a company where the top line is growing. As a point of comparison, Amazon was founded in 1994 and not profitable until 2003.</p>

<p>So if MS-DOS 4 was released in 1986, and it is now 2024, that's a 37 year gap between release and open source.<p>That means Windows XP should be open sourced by ... 2038. Not as far away as it seems. I'll add it to my calendar.</p>

<p>I have a lot of tech / healthcare couples in my friend group and this is definitely the arrangement. Especially true since healthcare careers have very different timelines than tech.<p>In once instance, one partner is a clinician and absolutely has to be on site 5 days a week, not counting on-call. The other works 100% remote but the company is global, so depending on the week they may be on Europe time or Australia time.<p>This is definitely a work arrangement I couldn't have imagined being common 10 years ago. This shift will likely be one of the defining economic changes between the 10's and the 20's.</p>
