No, because if you think about Startrek the endgame is replicators. Well the concept that 100% of basic needs are met.

At some point work becomes unnecessary for a society to function.

Why is that the endgame with people though? Maybe I'm just jaded but several different human nature elements came to mind when I read your comment:

Greed/Change Avoidance:

If someone invented replicators right now, even if they gave it completely away to the world, what would happen? I can't imagine the finance and military grind just coming to an end to make sure everyone has a working replicator and enough power to run it so nobody has to work anymore. Who gives up their slice of society to make that change and who risks losing their social status? This is like openai pretending "your investment should be considered a gift because money will have no value soon". That mask came off really quickly.

Status/Hate:

There are huge swaths of the US population that would detest the idea that people they see as "below" them don't have to work. I can imagine political movements doing well on the back of "don't let the lazy outgroup ruin society by having replicators".

Fuck the Poor:

We don't do the easy things to eliminate or reduce suffering now, even when it has real world positive effects. Malaria, tuberculosis, even boring old hunger are rampant and causing horrible, unnecessary suffering all over the world.

Dont tread on me:

I shudder when I think of the damage someone could do with a chip on their shoulder and a replicator.

The road to hell is paved with good intentions:

What happens when everyone can try their own version of bio engineering or climate engineering or building a nuclear power plant or anything else. Invasive species are a problem now and I worry already when companies like Google decide to just release bioengineered mosquitos and see what happens. I -really- worry when the average person decides a big complicated problem is actually really simple and they can just replicate their particular idea and see what happens. Whoops, ivermectin in the water supply didn't cure autism!

Someone give me some hope for a more positive version here because I bummed myself out.

Does it? The Communist Manifesto famously hypothesized that those who have the replicators, so to speak, will not allow society to freely use them.

The future is anyone's guess, but it is certain that 100% of your needs being able to be met theoretically is not equivalent to actually having 100% of your needs met.

We have to grow out of those kind of dreams. That's like a kid dreaming that when he grows up he'll eat ice cream for dinner every day.

People when they mature have an innate desire to work. It is good for body and mind. If you're curious about the world, you'll have to do some work one way or another to achieve your goals and satisfy your curiosity.

If "society" is just a function of basic needs, then there's plenty of places in the world to visit where people live like that and use any excess energy in endless fighting against each other instead of work.
