They don't know the surface like how we don't know the bottom of the oceans

Idk if there are enough resources to create an advanced civilization underwater, let alone that deep

That's from our perspective though, another species would have different needs

Yeah but how do you forge metals underwater

They'd be very limited in just that one avenue of tech

I bet if we asked a real smart person they'd think of way more disadvantages that even a deep sea suited life form couldn't overcome

Someone that is an expert on historical human development in all things cultural, technological, philosophical etc

metal isn't an issue even without forming an air pocket or just forging on a underwater volcano, some metals will even burn underwater for example (or explode when exposed to it).

Yeah there are lots of technological hurdles that I think are impossible to overcome for Merman Atlantis

The whole quenching process is mega fucked underwater

Iron and thus steel are yeeted because salt water would eat that ass

chelation maybe? no need to have heat at all if you just dissolve it in a container free from the ocean

aluminium, copper, brass

That would give shit metallurgy.

You need to properly quench metals to get anything reliable

The crystallin structure would be dog shit

And how are you gonna get free from the ocean in the deep sea

unless it's heated and enriched with carbon

so they can't build a bubble or dig a cave?

or tatch some seaplants

No, where would they get the air? Also the pressure is astronomical

And carbon enriching is going to be impossible if you're under water

You can't use ANY metallurgy techniques we use on the surface

Can't teach an old dog Jew tricks

volcanic fissures can provide a lot

That's toxic gas filled with chemicals that would oxidize metals

Ofc it could be non toxic to the creatures, but it would still fuck the metal

bigger issue would be that most weapons are useless except spears

even then, limited

Yeah you'd have to rely on non metal thrusting weapons

My gut tells me that life couldn't even get that far though

Intelligent life sounds impossible under miles of ocean

can't swing anything underwater, and throwing anything would fail as well

Hooks can be a weapon

Grabbing the opponent

What are you gonna use for a hook? No metal or wood around

Jagged rocks

Stone will be trash I think

That's not gonna be a hook

Actually not really

curious. Not counting their initial search engine and the ad business. What has google created (not bought) that hasn't been a complete shitshow and a massive failure
