I don’t agree with the conclusions he draws from his own analysis - almost all the issues and shortcomings he points out are related to technological shortcomings he admits - are already being addressed by the new systems - or are primarily issues with how drones are being used in the field - i.e. tactical combat decisions.
These are not inherently valid arguments regarding the effectiveness of drones as a new weapons platform - but with the current state of the technology and with the decisions on the battlefield
It’s early days, the technology will improve and the tactics will be standardized with time and drones will prove to be a dangerously effective tool - which has the additional scary bonus of being cheap and easy to mass produce and deploy
