Why that wide range? It is taking into account if we take active measures to diminish it or try to not make it worse, or keep running as if nothing is happening? Or just the uncertain of predicting a so complex system with so much unknowns as is the global climate system?
In any case, with so uncertain final impact, maybe food and water shortages will be just the tip of the iceberg. Rising the average world temperature so much (at least, for close to the worst case) should have a lot of very visible effects in all the ecosystems.
... but rationalizing it. Sometimes you just need to run more or less isolated single apps, not for a full blown OS. In a lot of usage scenarios is far more efficient, (both in disk/memory/cpu usage and app density) and probably more flexible. In others full OS virtualization or running on dedicated hardware may be the best option.
It also brings a virtualization-like approach for apps in the cloud. You can have cointainerized apps in aws, google apps and many others, something like having a vm inside a vm.
Is not the only solution of its kind. Google is heavily using containers in Omega (you can try their container stack with lmctfy), you can use openvz, lxc, or solaris zones or bsd jails. But the way that docker mixes containers (not just lxc by 0.9) with union fs, making them portable and to have inheritance, is a touch of genius.
The missing pieces are being added by different projects. CoreOS as a dedicated OS for containers (that coupled with etcd and fleet could become a big player in a near future), OpenStack/OpenShift bringing manageability, and maybe someone could bring to the table what Omega does with google containers.
Maybe those credentials were posted on github by devels and then scraped from there. Or from google, there is a bunch of id_rsa that pop up with trivial searchs.
Anyway, 25.000 linux/unix servers looks like a very low number, considering the 500.000.000 servers running apache or nginx, even with multiple domain hosted in a lot of them.
And if people start buying from that brand over rivals (or having country legislation forbidding not open enough and/or so backdoored hardware) it may move others to do the same.
Also, if a "hidden" functionality is exposed in major brands using that executable code to perform malware-like activities that brands should be punished in security aware circles. That won't reach the majority of people, but will be an start.
We were promised flying cars, home fusion reactors and hoverboards for next year. We already should had sent a tripulated mission to Jupiter, and the world should had ended 2 years ago. Sometimes our expectations have no grounds on the real world.
But anyway, maybe believing in some fantasies (like there is such thing as justice, and in this case, living forever) could improve things, maybe with that belief we could finally care about making our world to be sustainable in the long term.
They must get to you somehow. Widespread use of criptocurrencies mean that with social engineering, fake/trojaned apps or even using nsa backdoors your wallet is exposed for all the world. Social engineering is a powerful tool with bitcoin stealing trojans. Things are not so easy with bank accounts, even with all the problems they have, and of course, not with cash.
And if you don't want to rely in third-party gatekeepers, how most people will use it? In your phone? in your (for the majority, windows) pc? You can't use gatekeepers because a lot got hacked or just run with the coins, and you can't have them yourself because the most used platforms are ripe for external exploit, either making the user do something or just making popular good looking trojans.
And if that insecurity is not enough, having over that government sponsored weakened encryption algorythms and mandated backdoors don't help a lot.
We are still not ready for a distributed digital money in those terms.
To the systems programmer, users and applications serve only to provide a test load.
