Since making a fully flight-capable avian furry from a human IRL will almost certainly be a technological nightmare, I think I will probably stick with fully-emulated (with sense, smell and all the stuffs) virtual realities, and I believe these thing will emerge in a fairly near future, probably even less than 10 years.
And also, I sometimes come up with crazy conspiracisms and that including the thoughts that sustainable nuclear fusion with a decent energy output have already long since completed, but its development was then stopped via money/violence/sabotage/etc. by some corporations of the energy industry since this technology will completely devastate their business.
