Do "super", "hyper", "ultra", "meta" actually mean anything different beyond just being "cool prefixes" that cycle in and out of favor either organically or suddenly when a major entrepreneur just comes along and names their entire ecosystem after one of them?

imo: 
super - superior (perhaps literally bigger, e.g. superlinear)
meta - self observing, recursive (e.g. meta study)
hyper - beyond
ultra - very very

The only problem is externality pricing.

Those meanings are real, but on the other hand... if the Superchain had been a Hyperchain, and hyperstructures had been ultrastructures, would anyone have noticed? 😛

Good thing you didn’t name Ethereum “SuperBTC”!

Often the harder we rep the less attention we get. 

Instead of the “SuperChain” maybe something simple like “1Chain”
Or “BaseChain” would make more sense.

I think superchain feels more semantic than markety. It’s a chain of chains. Metachain might have also worked but somehow feels less capable, like it’s just an api to other chains rather than a chain itself

Agreed. The name encapsulates that it’s the “chain of chains”. 

“Metachain” seems reasonable but somehow feels like you’re trying to over-rep what its intended for.
