Any exponential curve looks flat until you scale it for the critical level which does the hockey-stick thing. I've read that we needed 1000s of physical qubits per logical. Now this is saying 100 or 12--that's progress. There was another story (Microsoft Majorana-based Topological Qubits) about improvements in decoherence/stability with scale.
