no, services is broken out separately.

>Most lost water for some stretch of time and some still don't have it.

This is extremely problematic. Power going out for periods of time less than 48 hours is one thing, losing water from the utility is a problem 3rd world countries have. You sure these people's pipes didn't simply freeze.

If its the utility, shame on Texas.

I have a similar but slightly different take. Though it was announced with tons of media hype and attention, this project seemed doomed to fail from the outset. Amazon, JP Morgan, BH may be giants in their own industries, but they're relative outsiders to the healthcare industry. We aren't used to seeing Amazon flop like this, so when it was announced, I think people expected that it would succeed. I think they're finding the limits of their long term strategy. Ultimately, Amazon is a supply chain, logistics, and tech company. JP Morgan Chase is an investment bank and services co, and BH is a holding company. IMO if they're really keen on upending the healthcare industry, they'd need to involve an industry player like Kaiser, who have existing infrastructure stood up and tons of relevant expertise.

I keep coming back to this in my head, thinking about how superficial this counterpoint is. Sure, if your requirement is that you pass regulatory muster, then lighting is "simple" in that you can buy an off the shelf bulb, socket, and housing. But those aren't the requirements. In reality, table stakes are LED DRLs, high beams and lowbeams. Matrix LEDs or laser lights that can mask out other vehicles using onboard IR sensors are becoming more common. Additionally there are styling requirements, such as computationally driven welcome and farewell patterns for lock/unlock, and trends to follow like light bars, super thin OLED strips etc.

A phone light is just a little LED you could buy for a dollar and put on your keychain.

Audi, BMW, GM, Ford dedicate entire teams to lighting, so no, a random engineer could not handle it solo.

Let me help you. I offered "Lights" as a design requirement unique to vehicles with respect to phones. Without any explanation it leaves the door open to a surface level counter point "Phones also have lights" that requires a functioning brain and the most basic level of reasoning. Lights on modern vehicles (high beams, low beams, DRLs, blinkers, brake lights) are certainly not simple components, especially those on vehicles sold in the EU where the regulatory body has taken up new technology much faster than in the US. This wasn't a dumb point, cell phone lighting requirements are child's play compared with the requirements of a vehicle lighting. It is 100% valid, but was also placed as bait as explained above. Make sense?

Especially hilarious given I left the "lights" bullet (with zero explanation as the last item) as fool's bait. It was gloriously taken.

Agreed 100%. Though even Sandy's conclusions are that they're saving at the margins here. It is revolutionary in the sense that they're design and manufacturing techniques are unique, but they don't lead to orders of magnitude reduction in complexity/cost.

If you're asking this question seriously, I have to ask a clarification question: what are we actually talking about? Are we comparing just certain aspects of production of the whole thing? If you think about this from an engineering perspective for even 30 seconds there are so many differences that come to mind.

- Pack has to go through an order of magnitude more charge cycles than a phone

- Must operate in a much wider variety of conditions than a phone

- iPhones don't need to drive themselves

- iPhones don't need to pass crash tests

- Brakes don't exist on iPhones

- Suspension does not exist on iPhones

- iPhones don't propel themselves at 100 mph

- iPhones weight orders of magnitude less than a car

- Regulatory requirements are way less stringent for phones

- Lights

- ...

I'm sort of dumbfounded by the level of conversation here given this is HN and the reputation is one of very thoughtful discourse on current events relating to technology and engineering.

EDIT: line breaks, looks like I'm further contributing to the downward spiral here.

I was waiting for the Muskians to swoop in and spread their nonsense.

Guess what? I drive a white model 3 long range AWD and I love it. I'm still 1: an engineer with 10 years of hardware experience and 2: skeptical of every ounce of BS Elon Musk has ever spread.

You know how many parts are under the car? Have you taken one apart? They're complicated machines with, again, orders of magnitude more parts than a phone. Forget ICE vehicles, we're just talking about EVs and iPhones. You don't think Tesla relies on thousands of suppliers? Who do you think makes the screens, wiring hardness, cameras, brakes, glass, acoustic devices, steering, battery temp management, motorized seats, etc etc. And who do you think supplies their parts? And theirs? And so on and so forth. Its a complicated web of suppliers and manufacturers, much more so than what goes into a single iPhone (which is still very complicated). This is why a Tesla costs 35k+ and an iPhone costs ~1k. There are more parts that are more complicated and manufacturing them takes more time, effort, and people. Elon may have a magic car printer in his wet dreams but that won't happen in reality for four, five, or six decades.

Also, nobody, I repeat, absolutely nobody is holding their breath for you to hit 1m miles in your Tesla. Currently they don't even have a story for repair and so many parts are fused that if something breaks you can't replace it. The car is totaled. I recommend you watch all of the early Rich Rebuilds on YouTube if you really want to understand some of the nitty gritty details of these vehicles. Yes they are simpler than a normal ICE. By an order of magnitude? Certainly not. Progress is made at the margins, in increments of 1% then 5% then 10% then 15%. Not 1000% in one swoop.

EDIT: clarification

Despite becoming more similar in recent years, the cell phone supply chain is still very different than the automotive supply chain. The number of parts/unit differs by an order of magnitude and so does the size and weight, not to mention manufacturing techniques and materials. These are capabilities, not so much skills, and they aren't as transferable as you may think.

For instance, logistically things are very different in the automotive space. Many, many more people are required to ship a single unit. You also have many more variables that can hold up a production line anywhere in the hierarchy because you rely on more 3rd parties for parts. While these things are also true of consumer electronics, you may rely on a dozen suppliers for an iPhone, car companies often rely on hundreds.

Materials are also very different in the automotive space. You have to build with materials that will last 100k miles driving a 80mph in all weather, day/night, freezing/scorching etc etc. It is a very long tail to cover. Apple can do it, but it will take years and many, many partners to get it done.

Having an android and an iphone and had two vehicles with both AA and CarPlay, I can confirm that android auto is a much better experience than carplay.

Eagerly awaiting a response from all the Muskian know-it-alls when Apple confirms their hardware/software relies on LIDAR.

Yes yes, wishing shame on another is beyond the pale.

Seriously, wishing someone feels regret, shame, embarrassment isn't incompatible with forgiveness. Learning difficult lessons, especially from harmful mistakes, is the only way society makes progress.

There was a lot of scientific information about psychedelics from the 50s and 60s. Illegalization and stigmatization of psychedelics was largely political and antagonistic towards the scientific community that was doing actual research. Also anyone curious enough to try out psychedelics will realize they're very different from narcotics. In the US there was always a subculture that accepted use of psychedelics, information passing through books, writings, unofficial journals etc. So to say the information wasn't accessible just isn't true. It may have been hidden, but if it was it was in plain sight and to anyone curious this world was easily accessible and accepting.
