Maybe I’m confused, but SIA doesn’t seem to solve for “we should expect civilization to collapse soon”.

Under SIA we apparently know that there are an unboundedly infinite number of people in existence, because that scenario is infinitely more plausible than any other. So the chances that we exist somehow somewhere are 100%.

But we don’t just exist somehow somewhere. We exist here and now as humans. And it still seems very odd that we are one of the first 110 billion humans if humanity is destined to produce 10000000000000000000000000 humans eventually. Them producing more humans doesn’t make our existence “more likely”. In either scenario every possible being exists, but it does seem to make near term civilization all collapse more likely.
