I think the article miss a big point: why war it will be? In term of definition of objectives mainly. If the objective is to exterminate another civilization, why not just launch an infinite number of small vessels that will crash on planets, space station and space ships? If it's controlled by an IA, who cares? the only thing which will matter will be economical sustainability. if the objective is to take control of a planet or a solar system, you are going to need big vessels, troops and other SF concepts. But I don't think anyone will care to take control of population. They might care about ressources and installation. Everything is so fragile, that it wont make any sense to try to gain control of it, the odds that every will be value-less at the end of the fight are simply to high!
