        ‚Bricked‘ used to mean unrecoverable without special tools. If it’s “just“ memory corruption, a simple reboot would probably fix it - no DFU restore (or worse) necessary, right?

        I know what "bricked" means dude. You don't need to explain to me what the word I just used means. Unbelievable.

        I've been getting these all day, it wears thin pretty quickly. Maybe you should put yourself in my position, and see how long you'll last before coming off a bit dismissive.

        Not bricked. Kernel panic. Equivalent to BSoD, but you reboot and you’re fine.

        Here is the context you're missing when you ran in shouting autism at a stranger like a 4chan troll, @SwissHttp is a fellow security researcher. Imagine one of your colleagues heard you say some simple term like "class", then sat down next to you and explained what a class is.

        Hey man - it's okay to be wrong; I'm wrong all the time. I'm not trying to pick a fight with you, nor is anybody else here. We just want the facts, and the way it looks, you said "bricked" and the devices just kernel panic.

        Of course he knows. But Natasha talks about a kernel panic. A kernel panic is bad. A remote bricking is terrible^100.

        And, honestly: If someone can destroy my devices from remote, I DO think that this is worse, compared to just a kernel panic that might be cleared by a reboot. 3/3

        If someone can take over your device, one of the things they could do is stop you from using it (why they would waste a valuable exploit doing that, i don't know). We are full-time professional vulnerability researchers, but thank you for explaining severity to us.
