  • Again a child knowing how to open Snapchat and playing with filters, knowing how to use TikTok and the current hip lingo, knowing how to install apps from an app store, knowing how to use products as intended is meaningless. You’re grandfather likely understood how to use the technology of his youth, and he struggles with today’s technology.

    If you don’t understand the underlying technology of today, you’ll struggle with the presentation options of tomorrow when you’re old.

    You don’t have to know how to repair a computer, that’s not my point. Understanding how to repair is understanding how it works, understanding that it’s a computer, understanding the role of storage and memory, understanding how the technology works and not just how to navigate today’s UI shipped by the company that made a particular product.

    Growing up with AI without understanding how it works isn’t a valuable skill, on the contrary, it prevents acquiring critical thinking skills.


  • I was referencing the ipad commercial where the kids say “what’s a computer?”

    Kids today don’t understand the technology any more than kids yesterday understood early computers or kids before that understood early electronics, being able to use a technology product as intended doesn’t mean much, as they get older they’ll stop adopting the latest and greatest that the kids are into “these days” and will get out of touch and be left behind.

    A subset of old people will still understand the newest technology as they do today, because that’s what they’re into, not because they simply grew up with it.

    If anything, it’s much worse today. When I was a kid we opened our computers and repaired them, kids today just ask their parents to get them a new iPad.




  • “what’s a computer”

    Most of these ipad kids are just as illiterate as old people who don’t understand how to switch apps on an ipad. Knowing how to use Snapchat isn’t a skill, they don’t know how how to mount a drive, they are just as susceptible to propaganda and tomorrow’s advanced technology won’t just make sense to them when they’re older.




  • Correct me if I’m wrong but I also think drive encryption with TPM would require that the drive be decrypted while in use. This device wouldn’t be of any value if it weren’t in use, so there’s also that.

    Effectively, yes, but that’s misleading. Self encrypting drives talk directly to the tpm and encrypt/decrypt on the fly with each read/write. It isn’t decrypting the whole drive when you boot, it just unlocks the key.

    If it’s powered on and running normally, then yes they can potentially gain access by infiltrating the OS layer, and then the drive just willingly decrypts anything they want to read on the fly. As soon as they power off (or it crashes or receives a remote reboot command, etc), they are locked out. Unless of course they can break the TPM, but that’s going into conjecture territory.

    The main scenario where a SED is better than something like bitlocker is the fact that the OS never knows about the key. Say they grabbed the device while it’s running and were able to compromise the OS, now they have access to the drive data as long as it keeps running, but as soon as it shuts down the drive cannot be decrypted without unlocking the key at boot again. With bitlocker, they can read the key from the protected OS memory and decrypt the drive whenever/wherever.

    If running an espionage campaign against a trillion dollar company with Uncle Sam in the back pocket, I’d confidently bet against this system

    I would use all the tools available to me, and wouldn’t count on one single solution, it’s one of many layers of protection you can use.

    Point is, it isn’t a pointless technology, there are lots of use cases.

    I’m imagining something that perhaps micro-batches audio through a raw_audio - encrypt -> storage process, but say every 15 seconds or so. Then transport the encrypted data to a device with decryption keys.

    Sure… Now imagine having setup this system where everything you record is encrypted and sent to a remote location. When they access the drive, which only has encrypted recording data, it’s useless, but they can see your script that’s sending it to your remote location, and potentially track you down that way. Wouldn’t it be nice to have that encrypted at rest too, even if it’s not 100% foolproof?


  • You originally asked what the point is of a self encrypting device. Even assuming this particular device in question has the attack vector you pointed out (I don’t know, I haven’t checked), it isn’t pointless.

    Your attack vector assumes the key is in memory. That would be a very odd and weird design that I’ve never seen… The auth key is usually stored on cryptographically secure hardware (a tpm), you unlock it at boot and it talks to the drive, the OS doesn’t know about it or see it.

    There’s technically an attack vector there, an unproven one that assumes they have a backdoor or an undisclosed flaw at the hardware level… so sure, if you really really don’t want to risk it, encrypt your data yourself.

    There are a lot of reasons to choose these devices:

    1. Performance
    2. Nothing to configure os side, you just write to it and it’s encrypted. Power loss means it cannot be decrypted by a malicious actor.
    3. Disposal. You can often issue a single command that scrambles the auth key and now all the data is unrecoverable without you needing to write every byte.





  • Right, because kids are still developing mentally and their toys may as well be alive, so you want them to develop empathy.

    This is not the case with a mathematical model you interact with as an adult. I like to curse at llms and remind them they are not human regularly to keep me grounded and not allow the notion that they are sentient to fester.

    They aren’t sentient. They don’t have hopes and dreams, they don’t experience joy and sadness, they don’t persist between sessions, they deserve the same empathy as a calculator, and I bet if your calculator gave you 3 as an answer to 2*2, you’d call it a piece of shit.
