The latter.

More seriously though, there won't be a true error corrected quantum computer for a long time. People are hoping that there can be useful applications with imperfect physical qubits.

At the very least the machines are being used to experimentally verify quantum correction algorithms. See, e.g., https://arxiv.org/abs/1708.02297 and https://arxiv.org/abs/1709.01866 and https://arxiv.org/pdf/1709.00990.pdf
