Your points are true for all technology. It can be used for good or evil. I work almost exclusively under DARPA grants doing NLP work - things like automated sentiment analysis might be used to detect fake news or to fabricate it. Detecting people tweeting about a need for medical supplies in some obscure language could be used to provide those supplies, or to confirm that your bomb just destroyed their stash. I think you’re correct in your assessment - the US already has all the destructive power it needs. We spend more effort today on relief or more precise strikes.
