There's a difference between strong and weak quantum measurements. Experimentally we can now even apply feedback on quantum states to stabilize them, which requires making partial, non-destructive measurements of a quantum state and then applying signals to correct deviations.
The whole talk about "wave function collapse" originated from the beginnings of quantum mechanics where the measurement process was poorly understood, in my opinion it should be replaced by the modern understanding, in which a measurement is a combination of an entanglement process between the system under test and a large external system, followed by decoherence caused by the many degrees of freedom of the external system. That produces wave form collapse, but it's not an abrupt or absolute process but rather a continuous, controllable one.

That doesn't imply that consciousness is special. The reason why you are aware of reading this, if you are indeed aware of reading this, is that your life matters for some future event, which on the fundamental physical level has already happened, but its exact results depends on how your life unfolds in some way. If I locked you up in an impenetrable box that is to be completely obliterated at some future point in time, so that whatever you do in the box would make no observable difference, the rest of your life in the box would not happen.

- ElephantsMyAnus 5y agoThat's an observation. Schrodinger cat isn't both dead and alive. Nothing happens in the box while it's closed. Really think about how this is an elegant solution that makes it completely un-paradoxical, excluding that events happen out of order compared to our intuition.
