No, I'm not wrong, I just don't like relying on "obvious" statements like "5 senses are better than 4". We can't know for sure what was "better" until the human race experiment is finished (and then we won't know either obviously).

Consider this: hereditary autoimmune diseases are usually seen as a disadvantage. However they were a huge advantage during the bubonic plague in Europe, increasing the chances of survival by estimated 40% [1]

If we manage to eradicate these disadvantageous genes we may not survive the next pandemic. I don't have the knowledge to predict whether deafness genes or some other property entangled with them will be advantageous 10000 years from now and neither do you. That's all. Now you can enjoy listening to music all you like, it's just beyond the point.

Hereditary autoimmune diseases are not a sense, and are irrelevant to this discussion about whether hearing is an objective advantage or not.

I’ll ask again, since you must have missed this question: is a deaf person, all else equal, more likely or less likely to survive and procreate relative to a hearing person?

You know the answer: it can be both ways depending on circumstances.

* In the prehistoric world I think he was less likely to survive. The difference doesn't seem to be dramatic though since these genes were not eradicated from the population.

* In the modern world the difference is close to zero with an unknown sign. Given that in developed countries probability to procreate seem to be limited by a desire to procreate, I can't rule out that e.g. deaf people for some reason have 0.1% more desire to have kids, or any other side-effect. So answer to your question is unknown, requires a study to figure this out.

* In the future hearing can be an advantage or a disadvantage depending on how the circumstances evolve. We see that species gain and loose senses depending on the environment.

EDIT: I would also like to clarify this part:

> Hereditary autoimmune diseases are not a sense, and are irrelevant to this discussion about whether hearing is an objective advantage or not.

It's a human trait which was "obviously good" in the past and is "obviously bad" now. Hence I don't trust statements that other human traits like deafness are obviously good or bad. It's interesting to discuss but it's not granted.
