Previously I wrote about the science fiction / comedy / romance series Upload on Amazon Prime. They finally came out with Season 2 which I just now finished binge-watching. I noticed that they are really exploring the ramifications of what the future could make possible including downloading.
I had been waiting until Season 2 came out to share with you an animated educational video on this topic from the YouTube channel Kurzgesagt -- In a Nutshell. Their video Can You Upload Your Mind & Live Forever describes the science behind mind uploading including techniques such as brain scanning. This future medical technology might not be available before you die so consider preserving your brain in the interim using cryonics.
