Hey Scott, thanks for doing this.

What do you think of the Copenhagen Interpretation especially in light of the delayed choice quantum eraser experiment[0]?

I know interpretation of QM is something actual working scientists try to avoid (I know I do such for my little corner of physics) but given how much interpretation informs intuition it's worth considering once in a while.

I confess I get annoyed when people make arguments about the interpretation of quantum mechanics using complicated thought experiments involving lasers and mirrors. Why not just talk about it in the modern way, in terms of qubits and states? :-)

For some of my recent thoughts about interpretation of QM, see this blog post, and especially the discussion in the comments section: https://www.scottaaronson.com/blog/?p=3628

I'm a laser physicist, so I think exclusively in terms of lasers and mirrors, but I get your point.
