Successfully uploading a mouse brain - and possibly also the radical extension of the lifespan of a mouse - would seem to me like it'd get as much media attention as Dolly the Sheep did. Has there been some MNT demonstration that would've gotten an equivalent amount of publicity?

Though judging from the reaction to Dolly, the reaction might be an anti-uploading backlash just as well as a positive one.

MNT == molecular nanotechnology?

There's awareness of MNT, but feasibility of the more extreme possibilities hasn't been demonstrated adequately for heavy investment. The roadmap from mouse brain to human brain is also much, much clearer than the roadmap from here to full fledged MNT.
