Those videos explained how altruism affects itself during evolution.

And I'm wondering: if the dissidents in China have similar movements, how would the number change over time?

(Here, I will just assume dissidents are good for the country. Also, assuming only dissidents will sacrifice themselves and alert others, possibly make other normal people into dissidents. ***And this idea is against the mathematical model discussed in the video, just a random thought. No serious political opinion was disclosed, aka I didn't say anything about if we need or we don't need dissidents in China. This is a proper disclaimer, and I do not accept any accusation for this random thought.***)

From the first video, if we don't know who is the dissidents, the result is not good. But considering those dissidents generally won't sacrifice themselves regardless, the reality won't be so bad. If dissidents can be identified by and only by other dissidents (unlike the green beard), things looked promising. However, when introducing the imposter, it goes terribly bad again.

From the second video, if those dissidents grouped together, it would be much better against different situations. But during that simulation, it's far from real-world situations.

Beyond the videos, I'm thinking about myself. I really appreciate those HKers, who can overcome their fear and fight for their own future. But in 2022, in China, I don't think there will be similar events happening in the future. And under this situation, when will be a good time to just move to another country, instead of trying to save this place?
