Mass data collection, recommender systems, social networks and AI models built on "fair use" of everyone's hard work of course.

They're all such noble pursuits, so much better than defense! Just look at how much they've done for the world.

Anything that doesn’t involve killing humans and destroying the environment?

I was hoping for a few specific examples. You might be able to find something with more abstractions between yourself and the killing and destruction, but if there are any 'pure' industries out there, there certainly won't be enough jobs for all of us.
