A real AI would have explained you that with great probability a room temperature (and atmospheric pressure) superconductor is not possible.
Few experiments were successful with small grains tested under enormous pressures. But apart from that a room temperature superconductor is unlikely due to the high entropy.
Antivaxxers are cartoonish characters created by the media to discredit those who opposed people in power. People like Trump or Bolsonaro said a lot of stupid and wrong things on purpose to discredit all the arguments. All the antivaxxers who appeared on the media are no better, actors playing the role of the idiots.
The opinion of the real opposition is:
COVID19 vaccines were available when the overwhelming majority of people already developed the antibodies on their own, therefore they were useless.
Viruses of that family mutate so frequently and are so contagious that there is no way to develop a vaccine on time. They will always arrive after people already came into contact with the virus and fought it off on their own.
Also the lock downs started after people already had their course with the virus and fought it off on their own. Lock downs were politically motivated, they saved absolutely nobody.
The story of the heart conditions looks like another false alarm to distract the attention from the real problem. Until now we used vaccines for a limited number of serious diseases and the vaccines were carefully tested over a long period. That was a sensible way to use vaccines because the mechanism is still not fully understood by science. Imposing by force two vaccinations every year with untested vaccines means playing too much with a mechanism we do not fully understand and nobody knows what the long term consequences could be.
The media and a lot of social media painted the killing of the CEO as a kind of revenge by a victim of the health care system. But to be honest carefully looking at how it was planned and execute I got a very different impression. It looked like a contract killing executed by a professional.
I don’t think that this event can be seen as a signal of the status of the system. If that interpretation were true we should see a lot more executives in the health care sectors being killed.
