How worthless is Philosophy?

--Also nice to see you again, dude. Hope you've been well.--

I remember talking to you some time before... you were saying that QM had a "measurement problem"... as in, QM as a theory couldn't define what a measurement really was. Has any headway been made in that regard since we last spoke? Or do you have any further thoughts on that at least?

I'm doing well, thanks.  I'm still working because they pay me too much to retire.

No headway has been made with the QM measurement problem.  The Many Worlds Interpretation doesn't solve it - it just shifts the problem from "how does the wavefunction collapse?" to "how do I end up in one of the Worlds and not all of them at once?".  That's an identical problem.

Most physicists punt the problem.  It is something that happens when the system-under-test interacts with the "environment".  The problem is that the boundary between the two is artificial.  Every system is something else's environment.
