Brains uploaded? What precisely do you think a human embryo is?
You'll have to read earlier in the thread and watch the videos to understand what i mean probably.
Simply, and EIS ship will have either embroyos, or more likely DNA which will likely be used to clone a copy of you. After that, emerging exponential technologies like brain uploading/downloading (circa 2025-2050 tech) will be used to rejoin the body, creating an exact copy of you down to your thoughts and memories. Think "syncording" from Arnold's 6th Day.
