yes, 1 is equivalent to an early filter.
2 would be somewhat surprising since there's no physical law that disallows it.
3 comes close to theology and would imply low AI risk since such entities would probably not allow a potentially dangerous AI to exist within any area they control.
4 is sort of a re-phrasing of 1.
5 is possible but implies some strong reason many would all reliably choose the same options.
For #4 and #5 what difference does it make whether biological beings make 'FAI' that helps them or 'UFAI' that kills them before going about its business?
Do you mean that an alien FAI may look very much like an UFAI to us? if so I agree.
1 is early filter meaning before our current state, #4 would be around or after our current state.
Do you mean that an alien FAI may look very much like an UFAI to us? if so I agree.
Not in the sense of harming us. For the Fermi paradox visible benevolent aliens are as inconsistent with our observations as murderous Berserkers.
I'm trying to get you to explain why you think a belief that "AI is a significant risk" would change our credence in any of #1-5, compared to not believing that.
This is the first in a series of posts I am putting together on a personal blog I just started two days ago as a collection of my musings on astrobiology ("The Great A'Tuin" - sorry, I couldn't help it), and will be reposting here. Much has been written here about the Fermi paradox and the 'great filter'. It seems to me that going back to a somewhat more basic level of astronomy and astrobiology is extremely informative to these questions, and so this is what I will be doing. The bloggery is intended for a slightly more general audience than this site (hence much of the content of the introduction) but I think it will be of interest. Many of the points I will be making are ones I have touched on in previous comments here, but hope to explore in more detail.
This post references my first two posts - an introduction, and a discussion of our apparent position in space and time in the universe. The blog posts may be found at:
