In the case of the LP to CD and VHS to DVD transitions, the dynamic was different. Owning a shiny new CD or DVD was a status symbol, so consumers were willing to pay more. The quality of the user experience was dramatically better on the new media. Also, CDs and DVDs were priced higher than LPs or VHS, so the business community made more money off of them. Even so, it took decades for the transition to really happen-- and for some older people, it hasn't happened even now.

In the case of TV to DTV, there was a government mandate to get the transition done. Enough said.

In the case of the Apple III, there were a bunch of problems. It had Apple II emulation, sure, but that was "intentionally hobbled" (according to Wikipedia). There were some plain old engineering mistakes like circuit boards malfunctioning because they were poorly designed. The Apple II was Apple's bestselling model ever, as a percentage of the market. They've never again had the same level of success since Steve Jobs decided to torpedo it and start with something completely incompatible.

Did Itanium kill off Alpha, PA-RISC, and the rest? Well, sort of. Intel made threatening noises and those companies basically decided to fold. The fact that Itanium was later a flop makes the whole situation kind of funny.

The truth is, though, it probably wasn't economically viable any more for those companies to compete with Intel/AMD in high-performance computing. Intel's process technology is so far superior to anything they have access to that that kind of competition is a joke. And the HPC market is so small that it can't support the kind of investment in process technology that Intel makes every year. HPC clusters now are built with Intel or AMD's latest, not with PA-RISC.

As I said before, it's a matter of motivation. Figure out who the key stakeholders are, and get them on board with the transition. Give them a reason to upgrade, rather than just telling them to do it for the good of the galaxy.

Well, sure, I agree. I just want to point out that this position is radically different from your previous position: the successful transitions always involved a "no regressions" philosophy where existing setups would continue to work just as well, or possibly better, after being upgraded. Backward compatibility is important, but it that important. You've already showed good case: Apple ][ -> Apple III transition. Apple III had some issues, true, but it was backward-compatible. And while it had some issues with compatibility it was not the problem. The problem was much simpler: price of Apple ][ was between $1298-$2638 (for 48KB) while price of Apple III was $4340-$7800 and price of incompatible IBM PC was $1565 (for 16KB).

Give them a reason to upgrade, rather than just telling them to do it for the good of the galaxy.

Well, sometimes you must do something "for the good of the galaxy" - in these case government mandate does wonders. The IPv6 designers were naive not because they refused to go with insane DJB's scheme, but because they insisted for 20 years that it's internal IT-industry affair. It was easy to solve the problem by forcibly moving everyone to IPv6 in year or two. Witness how fast the problem of incompatible phone power adapters was solved. Given the motivation ISP may do a lot to ease these transition process - but why should they? Nobody is paying them and nobody punishes them...

From the wikipedia article on the Apple III:

> Originally intended as a direct replacement to the Apple II series, it was
> designed for backwards-compatibility of Apple II software in order to
> migrate users over. However, since Apple did not want to encourage
> continued development of the II platform, they limited its capabilities to
> emulate a basic 48 KB Apple II+ configuration, with no access to the III's
> advanced features, a restriction which actually required custom chips to
> enforce.

So, in other words, the Apple III had backwards compatibility, but only of a crippled and limited kind. Itanium was the same story. It could run x86 code, sure-- very slowly.

> Witness how fast the problem of incompatible phone power adapters
> was solved [by an EU directive].

When the EU created that mandate, it didn't magically make existing power adaptors stop working. It just affected the adaptors that were shipped in the future. So this isn't directly relevant to the compatibility debate.

> It was easy to solve the problem by forcibly moving everyone to IPv6 in

Maybe this reflects my ignorance, but I don't see why that would be easy, even with a government mandate. If compatibility between IPv4 and IPv6 is an "insane scheme," then what is the alternative? Just don't use the internet for "a year or two"? Come back soon-- under construction!

Nothing happens instantaneously. Even recalls of tainted food take a few weeks to happen. The lack of any transition plan seems very foolish.

The ISPs are motivated, all right-- motivated to use IPv4. Let's count the reasons:

1. IPv4 doesn't involve disrupting existing customer setups.

2. IPv4 creates an artificial scarcity of IP address blocks, which makes those blocks a "strategic resource" for the companies that own them.

3. IPv4 will allow ISPs to charge extra for things that are now free. For example, having your very own IP address, as opposed to NAT privileges, will one day cost you.

4. IPv4 will eventually force the use of NAT. NAT will make it even harder for customers to use P2P programs. Since, at least in the US, those P2P programs compete with the ISP's own "content offerings," that's all gravy to them. Comcast would love it if the new shape of the internet makes bittorrent impossible.

I suppose one scheme that would have worked is giving everyone both an IPv6 and an IPv4 address-- then, taking away the IPv4 address after a few years.

The problem with this scheme is that, even if the US government mandated the transition, it's not clear that the rest of the world would follow. For example, France could decide that IPv6 wasn't such a great idea, and not mandate it. Since the US kind of likes being connected to the rest of the world, that would effectively derail the transition indefinitely.

Maybe it's time for a new saying to be coined: "If your transition plan requires a world dictator to implement, your transition plan is broken"

We've already discussed it...

Why will you want this? By the date X no new connections without IPv6 are allowed, after date Y all connections with IPv4 must be upgraded, by date Z IPv4 is disabled. Simple and effective. Witness similar transition working as planned.

Nothing happens instantaneously. Even recalls of tainted food take a few weeks to happen. The lack of any transition plan seems very foolish.

The idea that it can be done using "market forces" is foolish as you've showed later. Where "market forces" does not work government should. The problem here was that IETF did so much without government mandates they believed they can convince ISPs to do the transition.

3. IPv4 will allow ISPs to charge extra for things that are now free. For example, having your very own IP address, as opposed to NAT privileges, will one day cost you.

One day may cost you? "White" IP is rare commodity outside of US. It may cost you between $4 and $10 per month. Not a large sum, but if you'll recal that slowest NATed internet access is in the same price range...

4. IPv4 will eventually force the use of NAT. NAT will make it even harder for customers to use P2P programs.
Well, it's a problem only for unpopular stuff. If there are 1000 people with the stuff you need/want someone will have "white IP". Yes, in the distant future it'll be a problem, but not today. Low-bandwidth P2P uses automatic relays (think Skype).

Since, at least in the US, those P2P programs compete with the ISP's own "content offerings," that's all gravy to them. Comcast would love it if the new shape of the internet makes bittorrent impossible.

Yup. And you have limited amount of local ISPs to choose from. Often just one. That's why government regulation makes sense.

who is going to enforce the 'after date X no IPv4 only connections are allowed'?

there is no Internet Dictator who can enforce a policy like this.

Why do you need an "Internet Dictator" ?

Actually there is as shown quite recently. You can easily enforce such rule in a single country and for internations efforts there are WTO and other similar organizations. It's not like Internet exist in vacuum and can exist government regulations...

Yes, it's completely different approach from the existing one, but it's kinda strange to see so much energy expended on one kind of approach while another is completely ignored.

Um, I don't think Egypt leaving the wider Internet shows that international cooperation always works well. I'm sure that the US isn't happy that they did that. Rather, it proves that the Internet is a patchwork of national networks and governments will get the last say, no matter what the international community thinks.

The WTO's powers are not what you seem to think. It's not like the WTO can give marching orders Hu Jintao or Barack Obama. Rather, the WTO is sort of a forum for nations to talk to each other. Both China and the US, and a lot of other countries, have anti-free trade policies that the WTO is powerless to change. For example, the US gives tons of subsidies to farmers, who then use it to undercut farmers in the third world. China keeps its currency artificially cheap to pump up exports, and tends not to enforce any intellectual property laws at all (unless the owner of said property is Chinese.)

Or think about the 2010 United Nations convention on climate change. China and India basically refused to agree to any greenhouse reductions at all. With the greatest possible tact and diplomacy, they said "screw you." China builds a new coal-fired power plant every day and has no plans to slow.

International cooperation may work in the case of the IPv6 transition. Then again, it may not. Time will tell.

For IPv4->IPv6 to be like DTV we'd need for it to (1) only effect one country, (2) for that country's government to mandate that all new devices starting years prior to the cutoff date be compatible with the new system and (3) for there to be a millions of dollars allocated for the purpose of giving away compatible equipment.
