a lot

I guess I didn't mean a specific number but it would have to be in the trillions at least, right?

how deep would you want to go. And it would likely be in the nature of 10's of of billions.

If you want said city to self sustain with its own agragarian section and industrial portion, in the 100's of billions.

Well it costs $2.5 billion for a single submarine. So there you have a lower bound.

Who gives a fuck, the real question is how feasible is it.

Explosives would be horrible underwater since the medium is more dense meaning more forceful.

Remember also maintenance cost - corrosion would be brutal.

Two approaches: build structures on land and then sink them, or run a tunnel boring machine out into international waters and have it be entirely below the ocean floor.

They make corrosion resistant alloys with copper and nickel for oil rigs. They're more expensive, but they exist.

>>8971551
We don't have the technology to build underwater skyscrapers with windows.

Not too deep since the light coming from the underwater place will attract all kinds of sea creatures.

building underwater is impossible...
if even knives don't work underwater how can you expect to use hammer and nails
