As always, it's a two edged sword. The ability for a man to remake himself today is severely limited by the paper and electronic trail everyone makes. Modern medicine and dentistry are a scientific blessing, but we're entering Gattaca territory lately as it pertains to hiring. We have the ability to go online and learn almost any skill, read almost any book, view any art, listen to any music - but it is all tracked and can be weaponized for those following the wrong political fads of the day.
One cannot be connected to this new world and yet maintain privacy. Once cannot navigate this new world and yet establish roots.
It's all nomadic, gig society and neurosis from here on out until our robot masters put a remnant of us in their zoo.
