To be faiiirrrrr, the Ask HN was "most interesting," not "most exciting".
And it is very interesting watching the smaller (comparatively) country of Ukraine hold their own against a much much larger force in large part by using $50 Walmart drones with a grenade duct-taped on.
The large-scale use of cheap drones is going to change warfare tactics forever. It also leads to a bunch of fascinating anti-drone weapons, and then, of course, drones that can evade or are immune to such weapons will follow.
