I've been thinking about >>>/g/83557014 since reading it the other night and it has me wondering. The idea of an alternate history that's different from the one we experience led me to thinking about how we would disprove this theory 250 years from now, and I kinda realized, if you can simulate a human, you can run an android. From there it was a question about the appearance of immortality and snowballed into which families are most likely to be androids in hiding when we assume that the singularity actually happened like 800 years ago.

Supposing that any one of us can't disprove literally every time period other than the one preceding such developments, when would be the ideal time to start auditing very old and established families on the grounds that they might secretly be non-living parasites?
