A number of person-months, but not person-years.
Was there something written up on this work? If not, I think it'd be worth spending a couple of days to write up a report or blog post so others who want to think about these problems don't have to start from scratch.
At the FHI, we are currently working on a project around whole brain emulations (WBE), or uploads. One important question is if getting to whole brain emulations first would make subsequent AGI creation
If you have any opinions or ideas on this, please submit them here. No need to present an organised overall argument; we'll be doing that. What would help most is any unusual suggestion, that we might not have thought of, for how WBE would affect AGI.
EDIT: Many thanks to everyone who suggested ideas here, they've been taken under consideration.
