It’s one of the valid formulations of quantum measurement! However you can also look at path integral forms which produce identical predictions and still use real particles.
I’m not up to date on how folks square weak measurement with path integral formulations.
It seems eventually that particles will be seen as resonance points in a wave and not really discrete objects.
Wasn't it always somewhat obvious? That we and our instruments are only taking a snapshot of some continuum?
