I don't have any perspective, just state a fact - DARPA did contribute to things we find useful.

The core issue itself is terribly complex because in an ideal world we would never need military at all, and at least in Europe we had this hope that humanity is evolving in this direction, and that eventually even the wars in the Middle East and Africa will calm down. 2014 and 2022 were rude awakenings - there are crazy people out there, and they became nation leaders, and will start a war for one reason or another. That's why I don't have a unified opinion on that, especially that some military tech like interceptors are saving people's lives.
