3) Solana has huge throughput and speed and is cheap.
That means that it can support a *lot*.
Which means that you _can_ build complicated, intense things on it.
Which means people *are* building intense things on it.
Which take longer than simple things.
4) Some of the beta versions of these are fucking awesome.
Some will probably never make it to release--such is the nature of building products.
But some will.
5) Many are not previously crypto-native businesses.
When you have enough power, you can take a large non-crypto business, and put it on-chain, without losing functionality.
That, in the end, is what it means to be able to scale.
