A 2011 Sidney Coleman lecture (originally a Harvard talk, distributed on YouTube) arguing for taking quantum mechanics seriously, especially the measurement problem and the many-worlds implications of applying the theory to observers themselves.
Commenters call it a wonderful, clear lecture on what happens when you take quantum mechanics seriously.

Yes. It's been my defaultish interpretation since I've learned quantum mechanics.
There is a wonderful lecture by Harvard Professor Sidney Coleman, called "Quantum Mechanics in Your Face"[1]. In it, he essentially leads into precisely this. It's what happens when you take quantum mechanics seriously.
My issue is that I can't take quantum mechanics seriously, or expect that it's interpretational issues can be sorted out within itself. The problem is that quantum mechanics is "merely" an extremely excellent approximation to quantum field theory. It can be thought of as an "effective theory" in a very similar way to QFTs as low-energy versions of other QFTs. Which means naturally that we should expect the framework of QFT to answer the interpretational issues, especially to provide guidance as to how the changes due to the approximations change the interpretation.
This is all a fine idea, but quantum field theories have even worse interpretational problems.
