All the things we call personhood, will change, like the turing test we were so sure would define artificial intelligence.
Stuff we have to change when we clearly see a computer doing it.
In fact, one might argue, the only way you can tell if you are a person or not, is your genetic code.
Something that is formed, and never changes in less than 24 hours after conception.
Hope this helps (you see the light)
