Hobby systems like a small CNC mill or lathe usually don't need anything near 1µs (or better) max jitter. LinuxCNC (derived from NIST's Enhanced Machine Controller, name changed due to legal threats) runs fine on preempt-rt with control loops around 1kHz, with some systems you can also run a "fast" thread with say 20kHz and more to generate stepper motor signals, but that job is best left for the FPGA or an additional µC IMHO.

In austria, a women died of a heart attack while waiting in line to be injected. Just imagine what would have happend if the heart attack would have happened 30 minutes later, it would have been very hard to convince people the heart attack was not related to the vaccination.

I know of one other study (can't find it at the moment though) that specifically looked not for CT value but if they are able to infect cells. The outcome was something like vaccinated people do replicate virus, but the spikes of those viruses are (mostly) deactivated by antibodies and therefore not as infectious as virus obtained from unvaccinated people. In rt-PCR tests you can't really distinguish infectious from deactivated virus.

Although vaccinated people can be infected and even spread the virus, the disease is usually mild, amount of infectious virus and the time they are infectious is much smaller. And that is no speciality of covid immunizations, other vaccines like measles or influenza also don't prevent infection, but aim to prevent the disease.

The "not fully tested" meme is nonsense, many hundred million people have been vaccinated in the meantime, the safety profile is known.

Regarding long time effects beside immunity of vaccines, this interview https://lexfridman.com/vincent-racaniello/ goes into some detail. TLDL: there is nothing to expect/fear.

So I would be extremely suspicious of sharp clear properly exposed pictures of UFOs.
