Its possible to make 'chips' that small, but I'm not so sure they have
active chips that small. Active means it transmits a signal outwards,
constantly. Passive chips are activated by a nearby scanner at which point they then transmit.
It comes down to a power issue, and powerful satellites. I have been warning for a few years now that nanoscale powerplant technology had been
discovered:
Nano Free Electricity Generators, and Your Brain.
Next you'd need the right satellite(s). But another issue with the Sun's theory, in todays terms, is that a great many people are using nasal
'shots'. To do it that way the 'chips' would have to be nanoscale, and if they have such capability then they could just put them into the
drinking water supply, for instance. There is also another issue the technicalities of nanoscale devices being able to transmit thru your body, like
them being used for mind control I'd bet you'd need an army of them in there networked as a 'swarm' to be able to do the job. I'd argue they
probably do have functional early generation devices that handle this 'problem' in some secret labs, but them being ready for mass scale secret
implantation does affect the probability.
I'm not saying it isn't possible, nor am I putting it past "them", but I wouldn't worry about that just yet. However I'm pretty well known for
expressing alarmism about the future of nanoscale devices and things like mind control. These things are inevitable, whatever is indeed possible, so
we had better have a just system, not the current tyrannical one, as we enter the brave new world era.
