This usually implies he has great funding sources and very large lab. Being a "powerhouse" as a researcher is probably a different thing.

I know nothing about this person, but if his case is the average, he's probably got a lot of grad students doing the actual work. I can't tell you how many papers/patents I wrote only to be listed as the 5th contributor or some such thing.

I'd love to see a paper looking at this (e.g., how often is the "primary" author the last author or is the last author a better predictor of quality than the first, if you look back historically). I suspect this is very widespread issue.

So privacy will evaporate. Imagine dropping millions of these from a drone, carpeting a city. They'd be carried everywhere on clothing, animals, wind. Go to any location and scan for local cameras, download. Privacy will have to be redefined. We've done this lots of times. You hear what goes on behind the bathroom door, you don't say anything, you actually forget it. Because it's not polite to snoop. So in future eve…

This was the end of a science fiction novel from 1972, albeit the technology was an imaginary substance called "slow glass":

Conversely, imagine dual orbiting telescopes feeding into VR glasses giving us the perspective of a planet-scaled monster

That was a while ago. Somebody should rig up a pair of drones to a VR headset. Although, the head tracking latency might not work out...

RFID tags have no power source, and can do significant processing. As others mention, ambient electromagnetic fields can be harvested with a loop antenna.

What processing can an RFID do? AFAIK RFID can only store and send data, and are pretty "dumb".

This always makes me think I should go back and reread Brin's _The Transparent Society_ and see how it's held up to time. It seems pretty prescient from what I can remember.

this is fun stuff, my uncle did quite a bit of development on micro cameras

he worked on and made quite a bit on the patent for the first ingestible pill camera, and had some even smaller cameras for other medical devices that were even smaller (and fun to play with when I've visited a few years back)

I also bet many of these lenses can be stacked together to create a nice lightfield display...

I remember watching a docu in Netflix about spies where they show a deice that could record and transmit sound, using same technology.
