A lot of important technology do not exists yet for the above.
You assume independent movement and coordination of said movement in a hostile area, while we barely arrived at self-driving cars in well governed, 1st world areas (available only very few places afaik due to not being able to demonstrate high enough reliability to be convincing to lawmakers).
Point-to-point laser communication would be a great solution indeed, but that would also be a great solution for a bunch of other military applications. Yet it is not used, as we do not have reliable solution for working with it in case of moving objects (apart from satelites), too much coordination is needed to find the end points.
There is no software system currently that is even close to completing the requirements.
Let me offer a different point of view on the whole question:
A suicide drone is just a missile. Until recently there was just no way to propel and guide an explosive charge accurately, reliably and cheaply other than using a rocket engine.
A recon drone is just a helicopter. Until recently there was just no way to propel and guide a good enough observer and transmit the information reliably and cheaply other than a human carrying object using gas turbines.
What happened is now we have better battery and material technology, and way better (smaller) electronic devices (and optimized global supply chains). The cost advantage against missiles is mostly due to inertia in the military-industrial complex: most missiles in inventory were designed against targets with different size and performance parameters. You need a a million dollar AMRAAM missile to intercept an Su-30 flying 80 kms away, maybe flying at 2 mach or at 40 000 feet or pulling 9g maneuvers while dispensing chaff, flares and using EW. (and the missile carrying aircraft may have already pulled the same speed and maneuvers, and may have took off from the desert with 45 degrees Celsius and arrived to − 30 degrees Celsius flight attitude in the next couple of minutes, yet the missile must stay safe and reliable).
The infantryman did not get replaced. They just got missiles available in large numbers, and their own miniature recon helicopters in every bush. It is harder to hide and there are more precision fires to throw at you after getting spotted.
Thank you for sharing. For me your original talk is more convincing, and your Death Star strike plan is the one I would be more willing to follow rather than movie one.
I suppose this is an area where one can have a strong conviction on how things ought to be done, assuming other smart people think the same way, but in reality the way they think about it is closer to the base rate, so communication towards them should be as such.
