I fought in Ukraine and here's why FPV drones kind of suck

Sure, maybe. Or maybe it will be like Musk announcing what Teslas will be capable of in 6 months. We don't know, and the author doesn't pretend that they do. Don't forget that drones have been used in this war for years, and the vast majority of the drone industry has already pivoted to the military because it's easier to make money there. So it's not exactly "brand new technology".

But my point is that the author just says "from what I've seen, here is how it looks". And it seems like it has value.

When people say "the technology will improve", I think they're usually referring to the drones currently in use becoming much better not due to breakthroughs in technology, but by applying existing technology more effectively for military purposes. Current military drones used in Ukraine are inefficient conversions of civilian products that were never meant to operate under jamming, leave as small thermal signature as possible, etc. Original military designs, which are optimized for the battlefield rather than the local dog park, can be significantly better.
