  • Definitely a component of these safety systems needs to be actually effective driver monitoring. You have cars now doing gaze tracking, and tracking things like whether the person seems drowsy. Even while driving unassisted they will nag you if it can’t confirm your attention (I would get dinged sometimes on steep ramps because my arms would block the cameras while turning the wheel, it frankly trained me to reposition hands earlier just to not get the nag).

    I used the lane centering to help my kid get used to the sense of correct positioning in the lane. Of course turning it off to make them do it manually, but kind of like training wheels when the kid was tending to push it almost over the passenger line.


  • It can be a huge help, depending on the human factor.

    If it’s a ‘oh, take your hands off, it’s fine, take your eyes away, it’s fine’, then I could see that the systems replace human weakness but add their own, failing to reach a good “best of both worlds”.

    If it’s one of the systems that watches the driver’s eyes and nags if they take their eyes or hands off the task of driving while also encouraging good lane positioning and sufficient, yet perhaps uncomfortable braking in an emergency situation. Enough assistance to aid safety, still annoying enough to make people not rely solely upon them.

    Challenge is that’s not a very appealing promise of value. “Our system improves safety by using all this ADAS, but is annoying enough to keep you engaged!”.











  • So the real turning point in his riches to more riches story was Zip2. People have never heard of it because it was never anything even vaguely important, but it was a website in the midst of the dot-com era and Compaq, desperate to be “in” threw a bunch of money at it. Elon basically won a lottery.

    His next stop was to roll his winnings to try to get X (not the current one, an online payment platform) going. By all measures, it didn’t get anywhere, pretty well stomped by Paypal.

    In the midst of that competition, X folded into PayPal. Against all reason, they made Elon the head of the now joined PayPal/X, despite being on what was obviously the losing side of the business. It was a disaster and they ultimately sidelined him to save the company because he was so bad.

    Ok, so now he’s on the sideline but a large shareholder in PayPal… And there came $1.5 billion from eBay to acquire, and that got him to about a quarter billion, just for being there.

    Then the next significant stop was to jump on Tesla, rewrite their history to declare himself founder and largely let them do what they will while he collected the money. Sounds like in recent years he’s started to believe his own mega-genius hype, and has been imposing his direction more, and not to Tesla’s betterment.

    Like every step of the way, he either fell into lucky circumstances and managed to get everyone to feed his ego. I suppose his “skill” was taking credit for Tesla despite only being a source of funding way early on.





  • Lower storage density chips would still be tiny, geometry wise.

    A wafer of chips will have defects, the larger the chip, the bigger portion of the wafer spoiled per defect. Big chips are way more expensive than small chips.

    No matter what the capacity of the chips, they are still going to be tiny and placed onto circuit boards. The circuit boards can be bigger, but area density is what matters rather than volumetric density. 3.5" is somewhat useful for platters due to width and depth, but particularly height for multiple platters, which isn’t interesting for a single SSD assembly. 3.5 inch would most likely waste all that height. Yes you could stack multiple boards in an assembly, but it would be better to have those boards as separately packaged assemblies anyway (better performance and thermals with no cost increase).

    So one can point out that a 3.5 inch foot print is decently big board, and maybe get that height efficient by specifying a new 3.5 inch form factor that’s like 6mm thick. Well, you are mostly there with e3.l form factor, but no one even wants those (designed around 2U form factor expectations). E1.l basically ties that 3.5 inch in board geometry, but no one seems to want those either. E1.s seems to just be what everyone will be getting.
