In this analogy, the relevant concern maps for me to the notion of "safety" of airplanes. And we know what "safely" for airplanes is. It means people don't die. It's hard to make a proper analogy, since for all usual technology the moral questions are easy, and you are left with technical questions. But with FAI, we also need to do something about moral questions, on an entirely new level.
I agree that solving FAI also involves solving non-technical, moral questions, and that considerable headway can probably be made on these without knowledge about AGI. I was only saying that there's a limit on how far you can get that way.
How far or near that limit is, I don't know. But I would think that there'd be something useful to be found from pure AGI earlier than one might naively expect. E.g. the Sequences draw on plenty of math/compsci related material, and I expect that likewise some applications/techniques from AGI will also be necessary for FAI.
One of the reasons that I am skeptical of contributing money to the SIAI is that I simply don't know what they would do with more money. The SIAI currently seems to be viable. Another reason is that I believe that an empirical approach is required, that we need to learn more about the nature of intelligence before we can even attempt to solve something like friendly AI.
I bring this up because I just came across an old post (2007) on the SIAI blog:
Some questions:
I also have some questions regarding the hiring of experts. Is there a way to figure out what exactly the current crew is working on in terms of friendly AI research? Peter de Blanc seems to be the only person who has done some actual work related to artificial intelligence.
I am aware that preparatory groundwork has to be done and capital has to be raised. But why is there no timeline? Why is there no progress report? What is missing for the SIAI to actually start working on friendly AI? The Singularity Institute is 10 years old, what is planned for the decade ahead?
