1) The crypto that exists now will not change anything. If somebody who has developer skills starts a better path, like network ai coins, it could have an effect. The biggest problem is that so many people trust public key cryptography.

2) Crispr and similar tools allow the creation of bioweapons that target specific genetic lineages. Vaccines are a separate issue. Vaccines have a strong psychological component. *After WWII the U.S. made vaccines mandatory in occupied Japan as a psychological tool to weaken the Japanese. Go on Google right now and see if you can find a single reference to that program within 45 minutes.

3) The U.S. has been trying to reduce indigenous populations in Latin America for centuries, whether under guise of fighting communism, drugs, terrorism or whatever. Backdoored crypto like bitcoin and all crypto that depends on pkc will provide new opportunities to control and eliminate weaker groups.

4) Who knows how things will go. You do what you think is right, then you die and reincarnate.

*ETA
Just looked online and see
"Vaccinations were made compulsory in Japan after World War II as the U.S. military tried to suppress epidemics raging through a destitute and malnourished population. Armed soldiers rounded up civilians who did not comply."

Vaccines have long been used to show who is boss, a lot like armies sometimes use rape. The U.S. claimed it was forcing vaccines on Japanese to "suppress epidemics raging through a destitute and malnourished population", and of course they used nukes in Hiroshima and Nagasaki, not Berlin, because the radiation helped Japanese develop more of an interest in physics. Everybody pretends to be benevolent.

A vaccinated immune system is like somebody who cheats on tests. In the short term there is a payoff, but in the long term it makes a person's system weaker.

When a government makes vaccines mandatory they are using rape symbolism for psychological effect, but it is more subtle than overtly using rape to make a population submissive. Vaccinators come with a smile and since vaccines do often save lives in the short term they have an easy product to sell. If you research rape as a weapon of war  https://www.britannica.com/topic/rape-crime/Rape-as-a-weapon-of-war and look at how vaccines are used politically you will see similarities.

The United States spends a vast amount of money every year convincing people in poor countries that anti vaxxers are crackpots, that normal people should always submit to being injected by those with power.

There are two sides to the issue though.
