Call it what you will, an artificial afterlife, post-life memory care, a Google-L11-God complex, or about time there was an honest-to-AGI seastead.
There seems to not be any organizations, to use a term I learned from John L. Pollock, 'backward chaining' from the post-upload objective state towards good luck first response. This sort of planning algorithm involves backtracking on preconditions iteratively as opposed to forward propagating postconditions. They meet in the middle at instrumental robots of all sorts and sizes.
I think there are a couple problems with a fully-forward planning approach to WBE.
First, is that it is likely to be the case that uploading is much more expensive than preservation, but plausibly equal or less as there is a longer compounding investment and the investment remains honored within a civilization that both survives and continues to advance.
Revival introduces recurring memory and compute hardware costs which would likely be greater than preservations' method maintenance.
It would be quite an ironic tragedy to upload only to then become uneconomical, or through accidents, cybersecurity, etc 'die' because the original brain was destroyed and the visual data was not stored because it was extracted to a smaller data structure model during the scan, and the storage medium was not renewed or backed up, essentially. People tend to think that uploads cannot die because they can make backups. It is true that they could and would, but backups would introduce recurring costs or identity theft risks that could make life more difficult for ems.
Second, is that it is more likely that some data about a brain may be lost forever because we didn't know it was part of the requirements for sufficiency.
From what I understand, there are organizations working on microscale connectomics like Google and Allen Institute: but it seems like this is just more forward oriented pathfinding. The most important kind sure, but not the only time-direction. Eon Systems obviously has their 3D architecture pitch representing a sphere-and-cylinder insect-sized-tree afterlife for flykind.
I tend to believe the best path is focused on auxillary instrumental goals: particularly to build a successful game studio that creates high-fidelity world simulations with integrated algorithmic methods, applies game development software to invention and operation of robot fleets, and eventually designs and builds its own computer hardware for the endgame.
Current game studios generally tend to focus on entertainment, which has recently caused a lot of strife in the American industry as it naturally saturates in a zero-sum game, and therefore cripples the potential gargantuan money making potential of a more advanced game development market that works in the physical world.
Feel free to correct me if I'm missing something.
