None of the cinemas around here have such high quality equipment. Maybe they do elsewhere in the world but then catching a flight to see a movie that's better than what i can see at home isn't really a sound economic proposition.

Exactly this... Nowadays everyone already has a portable device capable of reading up to date content anytime anyplace. Buying a paper magazine or newspaper from the few places that still sell them and then carrying it around is massively less convenient. The only people doing this are generally the elderly who dont know how to use the newer technology, and obviously those people become fewer every year.

No i have a smaller room so i sit closer, so i have no need for such a large screen.
Plus i can sit in exactly the ideal location for the sound system and screen, whereas most of the theatre audience are sitting outside of the optimal seats.

Also theatre experiences differ significantly. Some of them have much smaller screens, lousy sound systems, dirty, smelly, crowds of kids, uncomfortable seating etc. There isn't a decent one around here, i have to travel a significant distance for a decent theatre experience.

Not really, both wechat and alipay have a tourist card option that you can top up with a foreign debit card. It has a 3% fee i believe but then you can pay for things the same way the locals do.

Modern end user devices are designed that way, as you simply cannot rely on a perimeter to protect portable devices that will be connected to all kinds of public wifi networks that you have absolutely no control over.

You can always add more wires, you can't invent new radio frequencies.

A company will be allocated a /48 or larger, and will allocate /64 blocks to VLANs themselves, so you do have a hierarchy.

It's the same in a lot of places - legacy traffic is through CGNAT unless you pay (sometimes a LOT) extra. If you want any kind of home server you have to do it over v6. Also makes it much easier if you have more than one device since you can access them directly rather than having to mess with non standard ports or proxies etc.

Vodafone are a mixed bag - depends what country you're in. They have v6 in india, portugal, germany etc while in some other countries they don't.

Only if you're relying on perimeter security rather than a zero trust model.

With a perimeter model the printer could be the access vector that gets you behind the perimeter.

Unless you want to physically go to the printer and plug in a cable, you'll probably network it, not that it's a huge problem really because you have to go to it to collect the paper anyway.

Creating an isolated airgapped network for the printer means you have to disconnect from your existing network first.

Putting the printer into its own isolated VLAN with limited access from wherever your user devices are works, but is more complex to set up.

If you're operating a perimeter based security model where you rely on perimeter security rather than each individual host then any compromised device inside the perimeter can be a serious problem. A printer will have an embedded computer and there's nothing stopping an advanced attacker from loading new firmware containing additional functionality.

So the problem is users having default passwords. A default which is generated from the serial number is a really half assed approach and only slightly better than the old admin/admin.
Serial numbers are sequential/predictable, so you could easily brute force if you know the algorithm.

For something like a printer there is a much better approach:

1) Listen only on the IPv6 link-local address by default - so there's no way to access it without being on the same VLAN.
2) Disable remote functionality unless a physical control on the printer is set.
3) Keep the admin account locked by default - require the user to press a physical control on the printer to temporarily unlock the account. You could even have it generate and display a random password to the user - either on an inbuilt display which most of these printers have, or by printing it.
4) Force the password to be changed the first time the user logs in.
5) Tie management to the first device used to access the printer, again requiring a physical action to reset.

Cisco hasn't made legacy-only equipment for a long time. Pretty much everything they have supports v6, and anything that doesn't is long past EOL.

If you're using IP addresses directly you're doing it wrong. DNS exists for a reason.
Aside from that...
v6 has a more sensible hierarchical approach, you have a prefix which in any business environment is going to be static - remembering that 2001:db8:: is your prefix isn't hard and then the whole company uses the same prefix.
Individual host addresses *can* be randomly generated using 64 bits, but they can just as easily be ::1 ::2 ::3 etc - if memorising addresses is your thing then choose an addressing scheme which facilitates that, so your have PREFIX:VLANID::1 PREFIX:VLANID::2 etc
Also avoiding NAT means that you have to remember one address, not an internal/external pair potentially with 1:many relationships and port mappings.

I guess you've never heard of a firewall.

Which would create an incompatible addressing system requiring a new protocol and larger addresses, and each country would still be limited to 2^32 addresses which would be fine for somewhere like Singapore but wouldn't work out well for the USA or China etc.
You'd also introduce new problems with a country prefix, like how to anycast something thats hosted in multiple countries etc.

Actually it's 127.0.0.1 vs ::1

For an airgapped network sure, you can continue using whatever antiquated protocol you want - NetBEUI, DECNet, IPX/SPX, Vines etc.

If you're going to provide Internet access at all you really need IPv6. You can get away with IPv6-only and provide access to legacy resources through NAT64. Most legacy networks don't have full dual stack and are encumbered by NAT44 anyway so the single stack setup is easier. If you have a legacy only network encumbered by NAT you're going to find increasing numbers of things are inaccessible.

In terms of small airgapped networks with static addressing its a wash - setting a static v6 address is just as easy as setting a static legacy address.

But in many cases for a small airgapped network v6 is easier - for instance you can use the link-local addresses which means no need for static address configuration or having a dedicated DHCP server for handing out addresses etc. Apple Airdrop uses this method for example.

"Barely adequate" is the enemy of progress.

If you had an area with no service and a sizable customer base then deploying new fibre is viable as you can quickly get a lot of customers.

For an area which is already served by some legacy technology it's much less profitable to deploy something new, depending on just how bad the legacy technology is.
The existing comcast cabling provides barely adequate service for a lot of people, so only a few enthusiasts and heavy users would switch to the new service.
Heavy users cost more to service, if you only have a few heavy users and the majority are light users then the light users subsidise the heavy users.

The existing comcast cabling is a sunk cost, so they have more headroom to reduce prices if a competitor pops up. The competitor has to recover the cost of deploying their new fibre so if a price war breaks out they're going to lose badly.
All of this discourages competitors from entering the market, and with no competitors comcast can keep their prices high. This also gives them vast economies of scale so even if competitors do emerge in some areas and they're forced to reduce prices, they can still keep their prices high in other places to maintain profit levels.
