So uh, how do we scale etherum's 150tps to that?

ZK rollups which greatly compress data on chain without losing security guarantees, combined with temporary storage using data sampling so each node only has to store a small portion of it. The zk rollups are live and support significantly more than 150tps today, and the data sampling goes live in November. There's a lot more work to be done but that puts the major pieces in place.
