> For AI, much of the war-fighting asset is software, which of course is free to produce after development, not expensive hardware. In an AI war, any software you push at thr beginning of the war will be useless within days, because the enemy will push better software. The most efficient way to adapt will be to continually update your algorithms by stochastic gradient descent on GPUs. In the resulting minute-by-minute arms race, hardware will be crucial, as will having clever engineers who can continually streamline the process.
