i'd agree with all you've said, but maybe citadel isn't the right word to describe it?
an image search gives you the impressiin of a world full of isolated bunkers, but thats not how you can compete with smart cities.

we need the focus on interconnectedness of those "citadels" and imagery or metaphors which inspire people for that, because otherwise the smart cities will suck up one citqdel after another - divide and conquer.

I dont know a good answer, but some infrastructure is well networked/connected and at the same time physically isolated or standalone. For example a scientific research station.

Sadly not decentralized, there are franchises too (e.g. 7-Eleven, McDonalds,...) or Remote Work Offices. Also Warehouses.


I wouldnt recommend any of the above over citqdel, but citadel might not be the best either...



Nexus? ...importanr point in a web of connections
Beacon? ...a signal reqching out across space
Sentinel? ....watchtower, but part of a network

To me, nexus seems best 😁
