For example I’m not aware of any way to do upload without a login in Seafile.

You can create upload share the same way you create a download share. Then just give a link to whoever you want to and that's it. I'm pretty sure it'll show files already in the share while uploading, but I'm not 100% sure on that.

Companies also probably have servers in other places, meaning perhaps they’d connect through elsewhere

Depends on company, but that worst case scenario is that all US companies would shut down all their services in Europe overnight. Every big player has datacenters around the world and if it's just the traffic between continents which is shut down then the effect is way less radical, absolute majority of Europe already connects to datacenters near them even if they use Microsoft/Google/Amazon/etc services.

For example with my employer dropping every US based company would be a hell of a work, specially if it's needed in a hurry. We, as well as a ton of others, rely on Microsoft services for all kinds of communication and should that go away we'd need to make quite a few phone calls around couple of continents just to set up a common ground on where and how to start building new infrastructure and how to keep communication lines open.

Though if it were for a few hours, maybe let people see the consequences of their dependence, and what life would be like without these services

Few hours is a short time. There's some problems around the globe all the time which affect various services on various levels for few hours all the time. Few days of complete blackout and C-suits start to really sweat (plus it costs significant amounts of money via lost productivity).

if anyone knows how to block connections based on location, feel free to enlighten me

You'll need a firewall/router which can do geoblocking. Based on quick search at least pfsense seems to have some options available. If I were to try that I'd set up a pfsense on a virtual machine, set up geoblock on that and use that as a gateway for my testing devices while leaving the rest of the network as it is so that I could limit/choose what devices may behave strangely and still have normal functionality for the rest.

I assume there's a ton of other options too besides pfsense, but the key words are 'geoblock', 'firewall' and 'router' or something around that. Also I assume that most of the stuff you find explains how to block incoming traffic based on geoIP, but it should be relatively simple to adapt those for outgoing traffic as well.

They didn't hack anything. Just your plain old DDoS attack which took the service offline for a while, nothing was (at least based on what I read) actually hacked (or cracked as old-school folks like me would like it to be called) or stolen.

It's the latter. But as a crapload of our everyday services depend on US companies and their servers it would be a service outage we've never seen before. Big US companies (Microsoft, AWS, Google, Meta..) could technically mitigate at least some effects if it's just the actual connectivity which is missing but if they're forced to shut down all European services it's a whole another matter.

For your everyday consumer it would mean missing a lot of streaming services, email, personal backups of your photos on cloud services and stuff like that. On some cases even access to their bank accounts would be lost. Depending on your usage patterns a majority of your digital life could vanish overnight. For companies it would be even worse, a ton of them rely on AWS and other services to keep their business running and all that would come crashing down and a massive amount of them would not have workforce, knowledge nor resources (money mostly) to switch over to something else. Also a lot of tax paid service rely on M365 and other cloud based stuff so they would be affected too, but maybe/hopefully not quite as badly as commercial side. Also, our credit card processors are mostly US (Visa and Mastercard) so a ton of money transfers would be halted as well.

So, it would be pretty much a digital catastrophe on government, commercial and consumer fronts for majority of the people. Technically there's nothing we couldn't rebuild on our own, but it would take at least months and more likely several years to get everything back online and the bill for that would be astronomical. And if it's a total kill-switch for US services then Europe would need new mobile operating systems to replace Android/IOS, new OS for their computers as Windows wouldn't work anymore and so on. And on top of that, GPS would go too, but with Galileo that might not be the biggest problem around. And also a ton of other stuff I can't remember right off the bat.

Sure, US would be stranded on the internet (and in the real world too at least to some point) after that and EU/UN/some other entity would take the role which is now on ICANN (and the same for other administrative entities). US would of course get a massive economical hit as well by losing all European customers, but on the worst case that would pretty much mean that the Europe's internet access, at least as we know it now, would end and something else would be built on the ashes.

But hey, at least I personally wouldn't have a problem to find a new job should I want to.

Is there a safe and private way to verify that I am in fact a real human on the internet?

In Finland we have this thing called 'mobile verification' which I use almost daily. It's a service where my phone number is verified to my identity in a secure manner (via multifactor bank account on my case but there's multiple ways to achieve that verification) and it works as an "middleman" where I can just click an icon on a website, feed in my phone number to the identification service, check MFA on my cellphone and then I'm shown a web page where the identity provider shows what information is delivered to an original website. Most of the cases, at least on my usage, it sends out my social security number, so that I can access my invoices, sign legal documents, check my tax forms or whatever I'm doing but the underlying system can provide pretty much whatever data they have stored. There's no technical reason why it couldn't be used to verify that I'm an actual human being too.

Say, if that was used in Lemmy (unlikely as the service costs something per each verification), identity provider would just send to my instance that I'm an actual human being but nothing else. The instance could then store that data and show a pretty blue checkmark next to my username without any personal data from me.

Disney+ subscribers will see interactive ads pop up as well.

The Mouse can fuck the right off with that. We've had subscription for quite a while since there's a ton of stuff for our kids but if they start to overlay shows with pop-up ads not unlike The Truman Show I'll rather set up a jellyfin server and dust the old pirate hat than continue to give them money.

Why would they even need an “AI” to run a power plant?

Because when you call your automation "AI", no matter how dumb PID or whatever you might be running, the product is at least 30% more fancy and gains more news articles, possibly funding and atleast some coffee with pastries and pats on the back to some front figure in a suit.

I think there already was case like this with either Google or Meta somewhere around Europe few years back. Or it might've been actual search results instead of extracts. The decision was overriden shortly as their web traffic dropped drastically. They'll 100% do this and don't think twice.

Generally, heating and cooling are the main energy consumption for domestic purposes. next up is the car, and then electrical consumption. (from what i remember).

I suppose it depends on where you live. Our house consumes something over 20 000kWh per year as our heating is also electric (and rest of the consumption is pretty neglible compared to heating) and we also have a fireplace which consumes around 15m³ of firewood, depending on how cold winter happens to be. Electric grid here has a ton of renewables and nuclear, so co2 footprint should be on the smaller side compared to global average.

Also, as google and microsoft (among others) shoehorns AI "answers" to everything that adds up, but private use seems to be quite insignificant anyways.

Several collections of login credentials reveal one of the largest data breaches in history, totaling a humongous 16 billion exposed login credentials. The data most likely originates from various infostealers.

Because its still bullshit.

Obviously. But I have no context on how much my actions create co2 in the first place. I assume driving a car generates a majority of it, or maybe heating the house, but I still don't have any clue how many kilograms that might be. But what I do know is how many kilowatts my house consumes electricity and at least roughly how much our appliances use, so if you want to try and blame me for consuming precious resources by generating text or watching a video at least give me an measurement I can easily comprehend.
