Basically people see an address like fdec:46f7:9b7f:1::3:20 and run screaming away about the complexity, seeing the address as a comprehensive indication of complexity, even though the real challenges lie underneath.

The whole 'traditional ipv4 just has 0.0.0.0' stuck in front of it is essentially exactly the same idea as, say 64:ff9b::142.251.152.119. Now there's also the likes of ffff::142.251.152.119 but that's just so software can pretend to speak IPv6 when the OS is really doing only IPv4. So they needed another prefix to indicate the network doing the v6 to v4 translation instead of the OS.

Anyway, the thing is that while it cosmetically looks more similar, it's not really solving the fundamental compatibility situation. It just "looks nicer" because it sticks to dotted decimals. However in practice, would fdec:46f7:9b7f:1::3:20 really be somehow less usable than, say, 120.30.204.78.167.144.120.209? The simple reality is that the 4 octet decimal pushed human usability enough as it was, and going to sufficient octets just brings it out of mere mortal reach. If you did want to say have more friendly local network addresses (the vast vast majority of human memorized IP addresses), then technically you could have fd::1, fd::2, fd::3, and those would all work and be super easy to remember (the ULA RFC says you are supposed to toss in 40 bits of random for good reason, but if you were using 10.0.0.1 style addresses, you would be no worse off with fd::1, fd::2, etc). You can even trivially have them live alongside 'real' global IP addresses, but ignore them whenever you want to just hand type a local IP address. You can even have something like a hex DNS. fd::f00d, fd::beef, fd::d00d, and so many more for your pleasure.

There's more features in IPv6 but you can ignore them since they are mostly for the machines to wrangle (the fe80:: addresses for example).

Note while you have cosmetic similarities to ipv4 addresses, the actual challenging part of that is the packet format and various translations.

We actually have a number of existing schemes for ipv4 mapping onto larger address space and the attendant NAT requirements. The presentation of addresses in an ipv4 looking way is the least of the challenges.

So don't take IPv8 seriously, it is slop and even in theory it wouldn't add anything new except a different cosmetic look to raw addresses and shortening the address space for no good reason.

Don't think you grasp which side has the actual leverage here...

The US market is the one that has driven the truckloads of money that have resulted in the memory vendor stock increasing over 10-fold.

Even a pretty severe compromise or fine is totally worth it to keep the money hose going.

Working from memory here

Nowadays that's a pretty expensive way to work

Well then you can change the sound of the car. You might have to bypass or add your own equipment, but you can do it.

Doesn't mean the manufacturer should reasonably be expected to make it even easier.

I can remove the exhaust (on an old car) and drive without it. It’s not efficient and not legal but I can do it.

Then you "can't" do it by the same logic. Because it's not legal.

Guess how that plays out insurance wise. Whatever liability coverage you think you have, forget it if you willfully disabled legally mandated safety features. Even if it's a motor vehicle accident where the noise wouldn't have realistically made a difference, even if the other party is at fault in practical terms, if they find out your car safety features were tampered with you could be on the hook without help of insurance.

[–] jj4211@lemmy.world 4 points 1 day ago

Which is why it can't happen for a safety mandated feature.

[–] jj4211@lemmy.world 7 points 1 day ago (1 children)

Since the sounds are to meet regulatory requirements, I doubt you'll see ability to use arbitrary noises, at least for the exterior noise.

[–] jj4211@lemmy.world 1 points 1 day ago

Good catch, this could be a little piece of a much more credible larger body of water, we just can't see the connection from this angle.

[–] jj4211@lemmy.world 1 points 1 day ago

Yeah, this too, "Need someone very familiar with..." HR translates to "10+ years experience" without even a thought.

Pallative care suggests the thing is going to die. The stuff that is still mainframe or still DOS at this point is going to be that way to the end of time and is immortal.
