Assuming @MidnightNetwork will replace Privacy Coin (like Monero) is a fundamental misunderstanding of demand. This is not a technology race, but a confrontation between two philosophies: Absolute privacy and Conditional privacy.
Traditional Privacy Coins are rough but sturdy "fortresses". They cut off all observation, require no explanation, and need no permission. In contrast, Midnight is an intelligent "filter". It doesn’t hide everything but only hides enough for you to be both private and able to prove validity (via ZKP) to the system.
Midnight allows for "selective disclosure". However, as proving becomes easier, it will become a mandatory requirement. Privacy shifts from a default state to something users must "justify". You are not forced to disclose data, but you are compelled to "prove in the way others want".
Midnight doesn’t kill Privacy Coin through technology, but by changing societal expectations. As pragmatic privacy takes precedence, the demand for absolute anonymity can easily be deemed "extreme".
Midnight does not replace Privacy Coin. They are two diverging paths: One maximizes personal freedom, while the other optimizes balance to integrate into the system. Midnight may win in user scale (mass adoption), but Privacy Coin remains the final refuge for those who refuse to "justify" their privacy.
