Because that immune system(if one wants to call it so) is within the eyeball,not on the outside. Lacrimal immune response is something else again.
Overall:
It's called Immune privilege and is present in the central nervous system, the uterus and the testicles as well.
It's nowhere near as extreme as the comment OP posted thinks it is - if you think about it closely it doesn't make sense.
The interior of the eye is highly vascularized and of course "regular" immun system parts go through that.
In reality it's more like"the eye" has an "extra Immunsystem" that helps it keep its special structures functional. Both alone as well as with the help of the body's main system.
Dude, don't you think we tried that?
The first time we got Schickelcutlerstalin for some reason who killed everyone with his out off-control biological weapons.
Then for some fucking reason we got a fucking snake hitler!
And now we are all out of time-travel juice and locked down in a reality where hitler lived AND an orange is also hitler.
Well, I had a little bit left,but a giant testicle came along, kicked me in my testicles,shouted "you want fucking Mother Theresa torturing everyone to death" and disappeared.
The war started in 2014 but somehow half of Europe and all of the US forgot.
Not to mention what happened in Georgia.
Or what happened in Chechnya.
Or with people living in Moscow just because Putler wanted to start a war.
Or journalists.
Sorry,but Russia never was a beloved uncle.
Russia was always the "shady, violent, uncle who can't keep his hand off his kids but everyone ignores that because some family image they need to uphold and furthermore while he is quite poor he makes great gifts to the rest of the family. So everyone tolerates him."
Around 30TB shares between various providers.
Hetzner for servers, Ionos for S3 compatible block storage, Tuxis for PBS, atm still some old backups at Synology and Backblaze,but getting rid of that.
Netbox for the actual hard "inventory" like documentation. What cable goes where, what powers what, what MAC is assigned to what, when did I buy this or that?(The later with an addon). In theory I also have snipe-it,but doing it all in netplan is more convenient.
Wiki.js for the concept and How-To-Side. Lots of draw.io diagrams (which can be done directly in articles), HOWTOs as a reminder for me, naming conventions, etc.
Also some basic inventory information for disaster recovery. (Wiki.js is not hosted locally)
Vaultwarden for all secrets,passwords, recovery keys, ssh keys,etc.
Gitea for the most important config files/scripts/docker compose files.
And last but not least I do backups to Mdisc Blue Rays every few months. These include the documentation, the most important files (knx project for example), etc. and are stored at a different location (bank safe). There is also an detailled explanation in both my wifes and my own will how to access these so if something happens the kiddos or someone taking care of them can gain access.
Bonus content:
I am also banned at two different swinger clubs in two different countries. And I swear I was never a guest in either one.
First one: I am a paramedic and responded to a call to this establishment.Small, sleezy, club with not much going on. (We had a few od these in the area, I know how they usually look like)
Man had "too many to drink" according to the owner and he basically just called us to get rid of him fast.
Yeah, no. Guy in reality had a major stroke (subarachnoid hemorrhage to be exact) and was, well, actively dying. Not gonna tube a 120kg bodybuilder that is having seizures in a dark room. So I very nicely asked them to put on all the lights they could find. Which,well, did not fare well with the owner. He refused and did infact insult us and try to force us out. (With the patient)
He shoved me.
I am really not the guy you want to mess with when it comes to that. Former bouncer. Called law enforcement backup and shoved him back. Hard enough for him to fly through the room. Law enforcement arrived fast, arrested him and as then no licence holder was on site cleared the premises. (And according to them tipped off the fire marshal,the code enforcement and health control guys)
He requested the name of the manager of my service. Which was kind of funny....i was the manager. So two days later he wrote a heated mail and banned my colleagues and me.
The other one is sadly not as funny/expansive. During COVID I was regularly in the media(Disaster prevention/planning is my main business now) and after an interview with an national newspaper some owner took offence and wrote me a (actually fairly civilized) letter that I was banned for life in all his establishments. TBH, that one was FAR more difficult to explain to the wife than the first one.
I have a strong feeling, that someone who characterises himself as a "metaverse and web developer" that is interested in "super intelligence" might have other reasons why people do not consider him.
Don't get me wrong,he might be a totally nice fella and IT outside a narrow field of healthcare IT is not my field. But this guys makes all my spidey HR/management senses tingle hard.
Within most(or all) EU countries this would count as a continuation of business and all previous liabilities (e.g. employees contracts, customers contracts, etc.) would need to be honored.
Why it is done this way? To prevent people from doing exact that.
No, I was not an unruly patient,but instead called out their bullshit as a healthcare provider working with them. And reported them. Which lead to them banning me. Which funny enough is illegal here as well.
And I am banned from entering Turkey.
Turkish airlines nearly killed me during a flight by having some sharp pieces in my food. Had a gastric bleed from it,including a hospital stay in a foreign country.
Well. My travel insurance sued them and thinks got ugly. In parallel the political party I then was a somewhat active member of back then (as in "running for state parliament"-levels) was getting in arguments with Erdogan.
So one day I received a letter by my foreign department that I specifically should not enter Turkey or I might see a Turkish prison from the inside.
Look at you, on your high horse, who thinks that resources both are infinite and must be attributed to our little niche because your little morals think it's the most important thing.
Rather antagonising your own people if someone is willing to even move away one inch from your high morals to compromise with the rest of the world than to find an actual working solution.
Because then you wouldn't be able to fuss about it.
