This is heavily reducing the human experience. Even better technology and post-scarcity aren't magic solutions to all of the insanely weird evolutionary quirks/pitfalls/problems built into our monkey brains.
Having a planet of hyper long-lived people who never have to work hard, who are constantly fed without concern, fully dependent on advanced technology sounds like the context of a YA novel. In reality, none of us are hardwired for that kind of lifestyle. Hell, we're not even hardwired for this one. We're just messily and sloppily trying to hang on as we stumble forward. Core human conflicts and oppositions and disputes and wars and existential meltdowns and all of the other things our emergent survival consciousness deal with aren't going anywhere.
However, this situation will not continue indefinitely. An advanced, post-scarcity human civilisation will (hopefully) not face constant danger of war, disease and famine, Technology will still advance, but at a slower pace, and not in ways that significantly transform day-to-day lives. Human lifespan will probably also be significantly increased. The result will be a more homogenous, stable and static society. There will still be differences, bug huge disparities of economic and societal status will no longer exist.
In this environment, having no longer to deal with a constant background of threats to their survival, it's likely that humanity will have the time and space to turn to far longer term projects. Indeed, such projects will probably be the only way for a person to imbue their life with a greater meaning in such a future society.
