Several approaches are better than the break even point today, including the Google demonstration of error correction working to reduce logical errors: https://www.nature.com/articles/s41586-024-08449-y

There’s more citations to gate fidelity progress here: https://metriq.info/Task/38

Did the Google experiment actually hit break even? I got that it had only demonstrated that surface codes did what they were predicted to do. Is it really only a matter of creating more hardware at this point?

Yes it exceeded break even, but no you can't just copy paste hardware yet. For example, some kind of chip-to-chip coupling is needed since chips can't be arbitrarily large.
