On the right is a dancing constellation of dots resembling the fruit fly brain, set above the caption ‘simultaneous brain emulation’.

If Eon had indeed succeeded in uploading a fly - a goal previously thought to be likely decades away according to much of the fly neuroscience community - they’d [...] ---Outline:(03:43) A brief history of fruit fly connectomics[... 3 more sections]--- First published: March 19th, 2026 Source: https://www.lesswrong.com/posts/ybwcxBRrsKavJB9Wz/no-we-haven-t-uploaded-a-fly-yet --- Narrated by TYPE III AUDIO. ---Images from the article:
