I was a huge SpaceX fan from the early days so watched a lot of Musks presentations and interviews and noticed a lot of repetition and always felt he was strongly working from talking points combined with a reasonably good high level understanding of the topic.
He didn’t work as well off script and seemed to have stunted emotional development, not unlike a lot of internet age manboys raised on memes, video games and porn. It is difficult to reconcile his behaviour with an adult, father and manager of people and money. I suspect he has some seriously competent peiple around him like Shotwell who cover for his fuck ups.
IMO he probably is the kind of guy who can soak up stuff around him, turn it into a set of talking points and repeat it with the appearance of expertise. I think he may have had some cognitive decline due to age and lifestyle but I think he was a pretty competent bullshit artist in the past.
I am not an expert at anything but like many IT people discovered long ago that I can pick up most things in my general field with a bit of research. It is a dangerous mindset sometimes. There really is the feeling that with some basic undergrad math and comp sci and a weekend of googling you can understand quantum field theory and it’s totally delusional of course.
Unfortunately the fake it to you make it culture seems to have won. It doesn’t matter how crap you are, if you put yourself out there with confidence you will outcompete the quiet competent types. And when you get caught out there never seem to be consequences.
Most mobile/laptop devices should be encrypted by default. They are too prone to loss or theft. Even that isn’t sufficient with border crossings where you are probably better off wiping them or leaving them behind.
My desktop has no valuable data like crypto, sits in a locked and occupied house in a small rural community with relatively low crime (public healthcare, social security, aging population). I have no personal experience of property theft in over half a decade.
I encrypt secrets with a hardware key. They are only accessed as needed. This is a much more appropriate solution than whole disk encryptiom for my circumstances. Encrypting Linux packages and steam libraries doesn’t offer any practical benefit and unlocking my filesystem at login would not protect from network exfiltration which is a more realistic risk. It adds overhead.and another point of failure for no real benefit.
