I thought the delayed choice quantum erasure
experiment showed it wasn't the act of measurement that collapses the wave, but rather whether the information was retrievable or not.

Yeah, I guess in my statement I should have said “unless” instead of “until”, because it’s not time dependent. But it’s still the act of measurement, not the act of a conscious person looking at that measurement, that causes the collapse of the wave function.

That's not the case here; when particles are measured but the information erased/nonrecoverable it remains a wave:

That may not be the correct way of saying it. You can equally explain the data by phrasing it, “when the photon remains a wave, the which path information is nonrecoverable.”
But more importantly, you will get the same results regardless of whether a human being is there to observe it. It’s the detection of the photon (by way of interacting with the photon detector) that matters, not whether there is a person there to observe the detection.
