Correct, as far as I know. Note that the "idea" did not mention that the dog was to be cryogenized using the poisonous stuff we have right now. (I.e., one "solution", or part of it, might be to invent a non-poisonous anti-crystal substance or procedure.)
Anyway, the point of my "suggestion" was not that this would be some kind of "least impossible" idea, nor necessarily the most useful one. I'm not sure if you noticed, but I entered several proposals, all of which are very unoriginal. Although they are serious suggestions in the spirit of the post, I picked those in particular as a kind of humorous comment to the five-step outline of the post: All three "ideas" have in fact been discussed... often... around here, and pretty popular in theory. The "comment" is that finding worthy impossible things to do is trivial, and putting that as the first two steps in a five-step list of "how to do the impossible" is somewhat silly, kind of an excuse not to reach the hard steps. (Humorously enough, one of the ideas is "Do everything on the final list that gets more than 10 upvotes"; as far as I can tell, nothing got 10 votes.)
In the Muehlhauser-Hibbard Dialogue on AGI, Hibbard states it will be "impossible to decelerate AI capabilities" but Luke counters with "Persuade key AGI researchers of the importance of safety ... If we can change the minds of a few key AGI scientists, it may be that key insights into AGI are delayed by years or decades." and before I read that dialogue, I had come up with three additional ideas on Heading off a near-term AGI arms race. Bill Hibbard may be right that "any effort expended on that goal could be better applied to the political and technical problems of AI safety" but I doubt he's right that it's impossible.
How do you prove something is impossible? You might prove that a specific METHOD of getting to the goal does not work, but that doesn't mean there's not another method. You might prove that all the methods you know about do not work. That doesn't prove there's not some other option you don't see. "I don't see an option, therefore it's impossible." is only an appeal to ignorance. It's a common one but it's incorrect reasoning regardless. Think about it. Can you think of a way to prove that a method that does work isn't out there waiting to be discovered without saying the equivalent of "I don't see any evidence for this." We can say "I don't see it, I don't see it, I don't see it!" all day long.
I say: "Then Look!"
How often do we push past this feeling to keep thinking of ideas that might work? For many, the answer is "never" or "only if it's needed". The sense that something is impossible is subjective and fallible. If we don't have a way of proving something is impossible, but yet believe it to be impossible anyway, this is a belief. What distinguishes this from bias?
I think it's a common fear that you may waste your entire life on doing something that is, in fact, impossible. This is valid, but it's completely missing the obvious: As soon as you think of a plan to do the impossible, you'll be able to guess whether it will work. The hard part is THINKING of a plan to do the impossible. I'm suggesting that if we put our heads together, we can think of a plan to make an impossible thing into a possible one. Not only that, I think we're capable of doing this on a worthwhile topic. An idea that's not only going to benefit humanity, but is a good enough idea that the amount of time and effort and risk required to accomplish the task is worth it.
Here's how I am going to proceed:
Step 1: Come up with a bunch of impossible project ideas.
Step 2: Figure out which one appeals to the most people.
Step 3: Invent the methodology by which we are going to accomplish said project.
Step 4: Improve the method as needed until we're convinced it's likely to work.
Step 5: Get the project done.

Add your own ideas below (one idea per comment, so we can vote them up and down), make sure to describe your vision, then I'll list them here.
Figure out which one appeals to the most people.
Assuming each idea is put into a separate comment, we can vote them up or down. If they begin with the word "Idea" I'll be able to find them and put them on the list. If your idea is getting enough attention obviously, it will at some point make sense to create a new discussion for it.
