<p>>I suppose one solution would be to completely vet the training data such that nothing deemed "dangerous" exists in the data, which would be a huge effort.<p>I can see how this is tempting, but I suspect it would yield a naive model. I think the only way to improve this is to use a model that is legitimately advanced to support the concept of empathy, which may allow it to recognize others as being separate from itself, similar to how toddlers develop this sense (<a href="https://blog.lovevery.com/skills-stages/empathy/" rel="nofollow">https://blog.lovevery.com/skills-stages/empathy/</a>)</p>

<p>I think it's a side effect of the Transformer architecture. The worldview where all input is equally trusted, and there's no concept of "the other", makes it hard to build effective guardrails where some input is trusted and other input is not trusted.</p>

<p>SpaceX's entire history is full of, "there's no way they'll ever do X", followed by them doing it.<p>They definitely haven't hit all of their goals, but I don't think anything they want to do is impossible, just really difficult.</p>

<p>That's not necessarily true. Even spaceships in LEO will perform temperature-driven rolls so as to distribute heat and radiation. I have to assume that long-term ships like interplanetary transport will do the same.</p>

<p>I've considered whether our current transformer-based AI could be conscious, as I understand it, which I deem to include some degree of self awareness combined with some degree of external awareness. I can see how theoretically something could be self aware without any external awareness, but I grasp at straws when I try to envision what that experience could be like.<p>In either event, I think transformer-based AI can only be conscious during the act of inference. If that's the case, then the experience of consciousness that the AI is subjected to must be the content of the tokens in the context window and the activated weights. Maybe that's reason enough to be polite to our agents?</p>

<p>I worked at SpaceX at the time, and I cannot speak for the company, but I can tell you that approximately nobody inside SpaceX took the idea of a sniper seriously. There was a lot of internet talk about it, and it was one of hundreds of avenues that were explored, and ruled out basically as soon as it was explored.<p>The very interesting part of the liquid oxygen failure (and this was published in the investigative findings) was that the liquid oxygen that became trapped in the fibers was actually cooled and compressed into solid oxygen - you can read some details here: <a href="https://www.americaspace.com/2017/01/02/spacex-closes-amos-6-investigation-aims-to-launch-10-satellites-next-sunday/" rel="nofollow">https://www.americaspace.com/2017/01/02/spacex-closes-amos-6...</a></p>

<p>It was very likely the largest explosion in Florida spaceflight history. Considerably larger than when SpaceX blew up AMOS-6 in 2016, and that required a full rebuild of the pad infrastructure over 18 months.</p>

<p>I was fortunate enough to be chosen to talk to astronauts on the ISS from the ground and ask them a question, and as far as I can tell from searching this awesome resource, I think my question was unique.<p>I asked Ann McClain and David Saint-Jacques what experiment or module they would add to the ISS if they could pick anything. They both agreed that a rotating wheel that simulated gravity would be helpful for experiments and quality of life.</p>
