Famously Steve Jobs had a story about shaving time off of boot-up and equating it to saving lives on the concept of people sitting their waiting for the computer to boot up just lost that much of their lives. [1] I actually do believe there is value in thinking this way and it is one of my biggest arguments against TSA. Everything has a cost, including 'security' and 'safety'. If you look at the very real human toll, and economic toll, that airport security has caused any potential gain is out the window in just one day of costs from screening, and that doesn't even get into the privacy destruction this has caused. I think I would get way to angry to comment on that in an intelligent way.

But that is just one argument. My real anger at airport screening is that we have found it possible to fund and implement this level of screening, at massive monetary, human and privacy cost, but I can't go to my doctor and for a few pennies (sorry, those don't exist now, how about for a few nickles?) get a body scan that does all the 3d segmentation, recognition, etc etc etc. We could actually save lives if we put effort into this technology for people instead of for a sense of security. But we probably won't. Because fear gets money but solving real problems that actually impact people doesn't.

Airport screening of people doesn't yield those results. It's able to notice a big inorganic mass, or a chunk of metal, but it wouldn't spot a tumour, it gives nowhere near the level of detail that an MRI or CAT scan will give. The airport scanners are also much cheaper, coming in at ~250k USD rather than ~2m USD.

Even the xray machines used for bags, while expensive and capable, are designed to differentiate metals, liquids, and organics, not organics from other organics.

Both airport security and healthcare funding have their issues, but I don't think this is one of them.

This always strikes me as a weird thing tech people believe about medicine. Full body scans just aren’t medically useful for otherwise healthy people. You’ll inevitably see something and it’s almost certainly going to be benign but might send you down the path of a lot of expensive and dangerous treatments or exploratory procedures. This is why there’s always so much debate about prostrate exam and breast exam age recommendations. There’s a tipping point where the risk of iatrogenesis outward the risk of disease.

There’s alot to imaging. When my wife was battling cancer she was getting alot of MRIs and was in a trial for computerized radiology. We got to talk to the radiologist, who showed us the difference between what he found vs the machine. The machine spotted some stuff that he didn’t, but wasn’t as good at classification.

You also need context to appropriately interpret what you see.

Only in the Apple reality distortion field would I see the hubris of boot times being equated to saving lives. I see value in saving time, but without the celebrity worship, it's nowhere near the same in terms of importance, application, or utility. Besides, the same time saving desire has been a driving force in software by nameless developers since the beginning of software. Attempting to frame and attribute the concept to a single individual is dismissive and disrespectful to the work of others.

Wait what? https://en.wikipedia.org/wiki/Penny_(United_States_coin)

I almost exclusively take trains now because the experience of flying is one of repeated dehumanization, especially in the USA.

First, if getting dropped off in a car (most American airports this is your only option), you must suffer being screamed at by traffic cops while trying to navigate a perpetually under construction dropoff area. You get one (1) peck on the cheek from mum before some uniformed individual waddles over to yell at you some more.

Then you must wait in line at a check in counter behind fifty families with 4 large luggage items each, despite the fact that you only have a backpack. Why? Because when you tried to do online check-in and boarding pass, the site broke / said no, and the self-service check-in kiosk at the airport still isn't switched on despite being installed a decade ago.

At the check-in counter, a person who knows less than you about the country you're traveling to will inform you as a matter of fact that you can't get ok the flight until you buy a return ticket, since that's what their binder says and they don't understand your visa. You must wait for a supervisor to come and verify that your visa is actually valid.

Before security, you're offered the rich person line if you have the money to pay for it. Literally advertised as a "white glove experience." If not well, into security with the rest of the cattle.

At security, you get to be screamed at by TSA for not knowing the exact procedures of this airport you've never been to. Why must they have to tell Passenger, who is one person they see ten thousand times a day, over and over again that you have to push your box onto the automated belt yourself, rather than let it be pushed on as a train with the other boxes. Passenger must be stupid. Surely it's not because of poor signage that Passenger doesn't know what to do. And by the way, take off your shoes and let us look at your genitals. Oh, you don't want us to look at your genitals? Well then we'll have to just grope every inch of your body, and nut check you for making us do our job in a slightly more annoying way. Just in case you're terrorist scum, we'll check if you have bomb making residue on your skin, while someone else opens your luggage and digs around in it so everyone else in like can see what your underwear looks like. At TSA we offer full service sexualized humiliation, guaranteed!

The dehumanization never ends. Once on the flight you are packed in like cattle, so tight you're rubbing shoulders with the person on your right and left, while your knees dig into the back of the person in front of you. You're served a tray of slop that you have to pay for now. Security took your water bottle, but when you ask for water on the flight, it's given to you in a tiny plastic cup, that's free if you're lucky. Now sit there quietly while we try to sell credit cards to this captured audience.

Finally you land and it's time to get off the plane! Oh actually no, the curtain is closed in your face. Silly peasant, you must watch the first class passengers leisurely pack their things and stroll off the plane. Only until the last one is off may the dirty peasants pass the fabric barrier.
