As a layman the pathway seems to exist behind multiple massive materials science breakthroughs

How is it that we need to build logical qubits out of physical qubits for error correction purposes, but then still need to blow out our logic qubit numbers for error correction purposes, again? It seems like there's something missing from this explanation, at least.

the blow-up is in physical qbits
