wut? different QEC produce differently sized logical qubits and there are absolutely machines with enough physical qubits to amount to a logical qubit:

and realized QEC is definitely not far off

i'm aware and yet it's false to claim that these things don't compute. for the time being they're noisy computers but they're still computers.
