Is it better to addict children to gambling in mobile apps, or to build hopefully unused tools to defend those same children from invading rapists and murderers should the need ever arise?
Ukraine wouldn't exist if not for modern weapons systems.
If you love your peaceful life, you have war machines to thank.
America is secure, as is Western Europe, due mostly to terrifying war machines.
Keeping us all safe and at peace is something some might regard as truly noble.
I don't build weapons systems, but I would if I had the opportunity. It'd beat the shit out of predatory adtech and addicting kids to algorithms.
Moral questions aside, inertial navigation and guidance, fuze design, radar, multispectral optics etc are wildly more interesting problems to solve than "how do I hook whales for $700 in this shitty iOS game?"
Maybe we'll see an influx of new minds in defense now that Facebook and friends seem to be falling apart and firing everyone.
Maybe it'll make us all safer, happier, and richer (because war destroys wealth, and weapons can avert it entirely).
