Now I'm wondering, if one created a brand new dating app marketed "WE ARE NOT OWNED BY MATCH GROUP", would it make bank?
Whereas using our brains for compute (in the background, or during REM sleep) makes perfect sense; power efficiency is excellent.
- classical (Maxwell): electrons in the medium oscillate out of phase in response to the incident wave; this results in a new wave, propagating somewhat slower
- quantum (QED): incident photon couples to matter excitation (an exciton), producing a pseudo-particle called a polariton; it has a non-zero effective mass, resulting in propagation slower than c
As mentioned above, it absolutely isn't "absorbing and re-emitting". If that was the case, transparent materials would not exist (only milky/clouded ones), as re-emission is in random direction. However, photon propagation in the Sun is just that, a (very long, counting from the core to photosphere) random walk.

Now, a squad of soldiers, or even just one experienced rifleman, would prob. dispatch of such a threat quickly. But against (at most poorly armed) civilians it would be an all too effective terror/area denial weapon.
