Indistinguishable From Magic
I'm just watching a very interesting
British documentary on Prime Video (I stress British, because I've recently seen some non-British ones which are completely exaggerated!).
Don't be put off by it beginning to discuss UFOs. From 43 minutes in, it enters into a discussion of the possibility of the application of technology to the human body: applications which, for example, could improve or restore sight and hearing even beyond that presently possible to us.
That's what I found particularly interesting.
It even suggests the possibility of our communicating directly brain-to-brain by as early as 2045. I'm not sure I'd be very happy for others to be able to read my thoughts!
