Horizon: Never. Why? Wormholes don't do that.
Tech: Near infinite storage for nearly free. I'm pretty sure that in my lifetime most everyday people will no longer delete files or care how big something is.
Horizon: 10 years tops. Why? Moores law for data storage.
Tech: FTL
Horizon: 50-100 years. Why? I have a sneaking suspicion that there's some radical new theories about space and time just around the corner.
Tech: Androids
Horizon: 20 years. Why? Almost all the pieces are already here.
Tech: Artificial human wombs
Horizon: 15-50 years. Why? Kinda already here, just needs moral/political support
It's a thorny issue though. People are afraid of death but paradoxically this sometimes manifests in resistance to any efforts to address it. I think people have difficulty dealing with the idea of life extension in an equanimous manner, as the concept of death is loaded with fear.
So there will be arguments against it from many perspectives: psychological, philosophical, economic, religious and so on. These arguments can have merit and warrant due consideration but I think that fear and pessimism should be balanced with hope and optimism.
