NAT is not a security feature. There are multiple ways of exploiting the NAT logic inside your router to get inside. For example your router likely has logic to handle protocols that need connections into your network. It'll have to guess if you are using such a protocol, and there will be ways to trick it. NAT is not meant to filter incoming connections, it's just a side-effect under many circumstances. Keep in mind, NAT is not there to disconnect things. It's there to provide some sort of connection over otherwise unconnected systems.

So in any case if you don't want incoming connections, you must use things like stateful fiewalls, and those are just as easy to set up on V6 as on V4. Systems like OpenWRT already do that for you.

Well maybe the Internet is not exactly what you want then.

How exactly has IP6 been a nightmare? What makes is so difficult for you?
People keep saying IP6 is difficult, but once you ask them, they typically say something like addresses are longer and harder to remember (which they often aren't) or mention exotic and never used features like "IP-Address mobility" which nobody implements.

It's actually quite another issue. If you listen to people claiming that "NAT killed IPv6", that is a different point. IP is all about end to end connectivity. There are no special "server privileges" you need on IP-networks. It is like the telephone network. Everybody can do anything. You don't need special stuff to run your own "information hotline", you just get a connection and there you go.

If a person claims that "NAT is sufficient" it essentially means that they have given up on that. They are contempt with an Internet which does distinguish between those who have a public IP-Address, and those tho are behind NAT. It's a world dominated by large "hyperscalers".

IPv6 offers another Internet. It offers one, where everyone can simply run their own "webserver" from their bedroom. Everybody has their own IPv6 addresses. There is full end-to-end connectivity, if you open your firewall. There is no need to ask someone for permission to run your own IPv6 "server". It is a network that is free to anybody.

If you look into the world, you'll find logs of CGNAT, where your ISP is already doing NAT... often at great expense and often multiple times, particularly in poor countries where not even your ISP may have a public IPv4 address. In those areas IPv4 is, essentially, a closed system you cannot participate in. It's like an "Online Service" like AOL or Compuserve. In those places the only way to get actual Internet is via IPv6.

BTW we are already at roughly half the Internet traffic being IPv6, I've recently been at a colocation facility where they only provided IPv4 at special request... and that essentially just works.

Computer games like Excel are just one example of sports that people may find weird, but such things always existed.

For example in Germany in the 1970s there was a "Fußball"-craze. It's a game where 2 teams of up to 11 people try to get a ball into the goal of the other team. The hype around it was insane with TV-rights for an international tournament selling for _millions_ of Deutschmarks!
There was even a movie about that craze called "Libero" staring actor and singer Franz Beckenbauer, as a player.

While in the past it seemed like Java would run anywhere, from clients to servers, and even the occasional smart card, today most Java VMs are now SIM cards. While not an official part of the standard, SIM cards commonly provide a Java VM so operators can use the SIM toolkit without having to port their software to every single SIM vendor. Essentially this allows operators to have a more fine grained control over things like carrier selection on roaming, or formating numbers for outgoing calls. In some countries they even implemented "social network" type features in the SIM card, as that would work on any phone.

The point is that running code in your browser is a very dangerous and highly abused idea. It was back when Java Applets or Active X components were around, and it still is with all the "ad/surveillance" ecosystem draining our batteries.
Yes, there are use cases for this, but it seems to me that abuse of it is now much greater than any useful use. And even the seemingly sensible use cases seem like they make everything worse. Just look at Jira, for example. Pages take ages to load.

Yeah, a good ball-park figure is that you'll have about an eights of peak power on average. This can, of course, vary widely, but it's an order of magnitude.

So we could have those 21 GW of average power in roughly 14 quarters or three and a half years (give or take some years). Which is likely after the burst of the bubble. So those power plants will then displace a lot of fossil fuel plants because of their somewhat lower costs. Sure it'll take time, but only some years, not some decades. It's less than the time it takes to build a nuclear power plant.

Cycles of electricity prices will also make it more and more economical to invest in storage. Essentially it's a "no brainer" business model. You get some containers with batteries, hook them up to the grid (the inverters are typically already in the containers from the factory) and get a computer to automatically trade electricity. If a battery container gets to weak or breaks, either get it fixed or replace it while the others are still running.

Well the trick is that you are able to sell your services for a higher price than they cost you, for example by selling things people actually want to pay money for, but are actually cheap to produce.

I work in a company that does do "AI", but we have a different approach than most companies you hear from, we make, what's called a "Profit". We sell services for more money they cost us. I am aware that this is a very freaky business model in AI.

I have recently talked to the people more involved in the technical details and they said that it doesn't matter how advanced the model is they use and that cheaper models work just as well as more expensive ones... for their use cases. They also mentioned that they use older and cheaper "graphics cards" for their use as they are sufficient.

It could be, that once the bubble bursts and the demand for hardware collapses, that many of the cards currently in service will be used for many years to come. It's a bit like network equipment after the .com bubble burst.

I mean virtually all garage door openers have the ability to connect a button / key switch via simple contacts. Just use any "WIFI-relay", like the ones sold by Shelly, connect it and there you go. No cloud service or external company necessary.

I mean services like statscounter typically derive their statistics from Javascript run from ad- or tracking-servers. It is somewhat more likely that Linux (or BSD) users have something like noscript or an aggressive ad-blocker installed.
Then of course there is the point that many, if not most, Windows installations never load a webpage from the Internet. There is a huge chunk of people who use Windows for specialized applications without Internet access. It's a legacy platform.

I mean criticality is the most basic thing you need to reach in order to have a chance at any sustained fission.... if you have a high enough density of the right materials, it'll happen all by itself. It feels like that's something your "Nuclear Startup" would need to show to investors before you get any money.

... when everybody claimed that Bitcoin somehow offered "anonymity"... despite every transaction being available in an eternal unchangeable blockchain? (and despite the obvious attacks like the ones on bitcoin exchanges)

Looks like there's a new class of exploits, people who are stupid enough to brag about their crypto "money".

Programming languages are used for different applications. So while you probably could write physical simulation software in PHP, a PHP user is way more likely to write some sort of web service.

Essentially most of what the TIOBE index shows is how much different areas of computation show up in search engine results.
