Ok, given that the human brain might be “unnecessary” complex, getting uploading to run properly might be a bit trickier than getting simple forms of AGIs to work. So, I’ve delayed uploading technology by about a decade.
Yes, AIs would be forced to join peacenets to render them harmless to humanity. It’s an idea that might just work, but might hamper the freedom of AIs seriously, if the peacenets demand serious restriction to the power and influence of AGIs.
I’ve delayed introduction dispenser and materializer technology by a decade each. Maturity of those technologies would be reached even later. The ethereal materializers used for example in

for teleportation purposes are pretty much the pinnacle of that technology. The materializers of the early 22nd century are not nearly as fast, effective, and invisible as those.
