Now you can spend another few decades hooked on shitty drugs with shitty side effects made by shitty companies and an ever shitter quality of life before you die in your own shit in a nursing home.
Enabled mass migration from third world countries, created insane income disparities among farmers there, got us using shitty fertilizers that are insanely polluting and potentially dangerous to the consumer, causes yet another supply chain vulnerability that leads to instability, civil wars, and famine, and will verifiably cause the biggest famine in history once the system breaks down sooner or later.
I don't even need to bring up nuclear warfare (to which you're wrong since nations try and evade MAD all the time and we almost did have nuclear wars), I just need to bring up trench warfare, poison gas, etc. and of course biowarfare. Arguably advanced military logistics in general since that's where you get violent empires, sustained warfare, etc. as far back as the Assyrians.
Produced lots of pollution, is the leading cause of death for people under 40, has always been there to exploit people (just look how literally every part of the railway industry worked in the 19th century from people working on board the trains to the people who built the trains to the robber baron faggots running the railroad companies)
Exists to impoverish nations and peripheries of nations and enrich the core, nowadays does that with the entire world, spreads pollution, spreads evil ideologies and religions, allows small minorities of people control vast populations (this isn't just the Jews BTW, Armenians, Gujarati, Hakka Chinese, etc. do it too)
