I was imagining something more like concept-city based around an extensive quasi-Venetian canal network, where "swimmable" (like "walkable") defined a possible mode of regular transport.
Also swim-up bars.
Me too. I like to think that, if humans survive to reach some kind of utopian, post-scarcity state, people will experiment with building places like this, just because they can.
I just spent some time in Basel, so I thought they'd mention about how the locals go for a dip after work with their wickelfisch and float downstream back home
Or to work if your home is upstream.
I was expecting planning for climate change and the rising sea levels.
