Imagine an advanced alien civilization.

It's hard for me to imagine without some technologies. It must have some forms of AI, it must have some forms of robust smart contracts, it must have encryption.

Are they using paper money? Paper ballots for elections? What else seems implausible?

Not sure about an alien civ, but I see human beings using paper very far into the future as long as it's convenient, cheap and available. 

In the next 200 years we'll probably do away with a few things
- water for bathing
- combustion engines for individual transportation

As somebody who has an immense fear of needles I hope they figure something out something better there

Hard for me to imagine getting rid of water for bathing, but easy for me to imagine getting rid of paper.

I hear you on the needle front! <3

Possible, but shower-friendly water is much easier to come by (than drinking water). And on-demand desalination is getting better, especially as we increase our electrical capacity (great use case for excess electricity during off-peak).

California is maybe a good example, they had a long ongoing "take shorter showers" campaign to reduce water usage. Allegedly it was somewhat successful, but the step to "take *fewer* showers" is maaaassive in comparison. That requires a whole cultural/societal shift.

Back in the day, bathing happened a couple times a week at best. As fresh water becomes more scarce we shouldn't be surprised to see waterless bathing gain traction. Or a way to significantly reduce water consumption while bathing
