===== 2. There are many rival interpretations — no consensus =====

Your skepticism is supported by the diversity of serious alternatives that reject the observer-dependent view:

| Interpretation                         | Key idea                                                          | Observer role                                     |
| -------------------------------------- | ----------------------------------------------------------------- | ------------------------------------------------- |
| Many-Worlds (Everett)                  | All possible outcomes occur in branching universes                | None – reality is observer-independent            |
| de Broglie–Bohm (Pilot Wave)           | Particles have definite positions guided by a pilot wave          | None – deterministic realism                      |
| Objective collapse (GRW, Penrose)      | Wave function collapses spontaneously, not by observation         | None – physical mechanism causes collapse         |
| QBism                                  | Quantum states represent beliefs of agents, not objective reality | Observer = epistemic agent, not cosmic creator    |
| Relational quantum mechanics (Rovelli) | Facts are relative to interactions between systems                | Observer = any physical system, not consciousness |

So the Copenhagen view is one among many, and its dominance is more historical than evidential. It offers operational success in physics, but not metaphysical completeness.
