The point is because of the nature of quantum physics in having many possible outcomes there are different interpretations to quantum weirdness and this does not just apply to wave function. The many worlds interpretation states that there is no collapse of the wave function and all possible alternative of past and future are real and happen with varying states. The Copenhagen interpretation has the collapse being the interaction between the quantum world and the classical world and another interpretation the Von Neumann-Wigner the collapse is because of the measurement of the collapse in subjective terms.What does this have to do with the issue of observers?
Our eyes register photons just as scientific measuring devices register photons. There's nothing less "quantum" about either process.
There is nothing about the premise "quantum stuff is weird" that leads to the conclusion that only conscious observers collapse wave functions, especially when scientists make so much use of non-conscious mechanical observation devices to take measurements.
Do you think that physicists at CERN must have conscious persons stationed in the complex during every experiment, being told not to blink or they will ruin the experiment?

The fact is there are many scientists who support the observer being a conscious being despite how or what is used for measurement and only a human observer can make the results real. Many scientists say that reality does not exists until we are looking at it. Wheeler seemed to agree with this interpretation as well and he understood quantum physics more than most. So who is to say these scientists are wrong, just like scientists disagree on other interpretations of quantum physics.
Wheeler suggested that reality is created by observers and that: “no phenomenon is a real phenomenon until it is an observed phenomenon.” He coined the term “Participatory Anthropic Principle” (PAP) from the Greek “anthropos”, or human. He went further to suggest that “we are participants in bringing into being not only the near and here, but the far away and long ago.” [Reference: Radio Interview With Martin Redfern]
Wheelers delayed choice experiment was repeated and once again found the same results as his original experiment. In fact, it has been done at great distances and this shows that even if a light particle has been traveling billions of miles the act of measuring it can determine its past state. The delay in measuring still determined the state of the particle even after billions of years of already being in existence.
Physicists at The Australian National University (ANU) have conducted John Wheeler's delayed-choice thought experiment, which involves a moving object that is given the choice to act like a particle or a wave. Wheeler's experiment then asks - at which point does the object decide?
Common sense says the object is either wave-like or particle-like, independent of how we measure it. But quantum physics predicts that whether you observe wave like behavior (interference) or particle behavior (no interference) depends only on how it is measured at the end of its journey. This is exactly what the ANU team found.
"It proves that measurement is everything. At the quantum level, reality does not exist if you are not looking at it," said Associate Professor Andrew Truscott from the ANU Research School of Physics and Engineering.
Experiment confirms quantum theory weirdness
Some scientists interpret the observer effect to imply that consciousness is needed because without a person (scientist) looking through the measuring device or just looking at the data from any scientific tests there would be no data, or quantum experiments. Some scientists believe that all things have some form of consciousness (panpsychism). The fact is we don’t completely know and that is why there are different interpretations regarding quantum wave action.
Wheelers “participatory anthropic principle,” states “We are participators in bringing into being not only the near and here but the far away and long ago." and that a human observer is key to the process and Every piece of matter contains a bit of consciousness, which it absorbs from this proto-consciousness field.
