Estimates say that we will need about 1 million qubits for practically useful applications
4k logical qubits can be enough for breaking RSA/ECDSA
And, the Google recent discovery is not about 105 qubits, but about error correction is improving with increasing number of qubits, exactly opposite to all previous approaches. And that's the only crucial thing here.
In other words, you won't simply need milions of physical qubits anymore - to reach 4k logical level.
