> iPhones definitely have lights.

I am sorry, are you trolling?

Are you seriously comparing smash test on a phone with regulatory crash test on a car? Have you thought about this at all? Do iPhones have crumple zones designed in? Do they asses performance of the chassis after 30 years of corrosion? Do they operate in 50 degree Dubai or -30 Siberia? Do they travel at 100 m/h? How many Gs does an SSD (~100) survive as opposed to a human brain (~10)?

I am sorry for namecalling, but this post comes across as very arrogant.

I could just as easily ask you whether cars have to engineer at the scale of 5 nanometers. Or whether cars have to support thousands of third party engineers adding arbitrary add-on components. Or whether automakers worry about hardening their security against nation state actors.

I'm sorry, but do you honestly believe that automobiles are more complex from an engineering standpoint than microelectronics? How could you possibly explain why the microchip was invented 100 years after the automobile?

Every domain has its own engineering challenges. Apples has consistently shown execution excellence across a wide range of disparate areas though. And more importantly an ability to quickly and effectively spin up expertise in new areas. From silicon to machine learning to acoustics to compilers to optics. Read this HBS case study[1] to be amazed at its ability to leverage cross-functional expertise across disparate domains. No large org in the world operates like it. There's a reason AAPL has a 50 times the market cap as GM. There's zero doubt in my mind that if Apple pursues autos, within a decade they'll acquire 5%+ global marketshare.

Tesla designs its own chips, they don't use 5 nanometers but they are working on 7 nanometers. You need to have very good microelectronics to build a modern car.

Yes, car makers have to worry about hardening against nation states. Probably don't do it as well yet however.

However I agree that Apple could go into that direction.

'whether cars have to engineer at the scale of 5 nanometers'

Thats done by TSMC, but you are right, I have much higher confidence in them producing a car than I do in Apple.

> do you honestly believe that automobiles are more complex from an engineering standpoint than microelectronics?

By two orders of magnitudes, at least! Modern car encompasses microelectronics, safety critical software and hardware design, passenger safety, repairability, corrosion, and thousands of other issues phones and laptops never face. You can't just push an OTA and fix a flawed engine. You can't tell you users 'they are holding it wrong'

How do you explain that Segway was invented after the microchip?

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

Did i say arrogance?

Joke's on them, I was only acting dumb!

Seriously, you putting a bullet point with no explanation, and got an equally terse rebuttal. You didn't "win" that.

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?

Lights are highly regulated but they're very straightforward regulations to follow. If you're not even going to bother to write out a sentence then it's not worth responding to it seriously, because it's hardly a reasonable objection in the first place; any random engineer could handle it solo.

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

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.

> 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.

Yes they are. You don't get to point to random fancy things and call them "requirements".

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

You're taking "phones have lights" too seriously. It was a deliberately vague and useless rebuttal to a deliberately vague and useless point. The real answer is what I already said. Replicating the functionality of a bulb/socket/housing is not hard to such an extent that the only reason to bring up lights is for jokes. So the joke got a joke back.
