You will always find a use for surveillance, and in capitalism there is a natural incentive for those developing these technologies to find all the possible uses and push them aggressively and handwave objections. At this very moment there are thousands of sales people pitching it. But this is where civil society and principles like democracy, liberty and privacy step in to temper the worst impulses and greed. Unfortunately that tempering mechanism is currently nonoperational and anybody with a tag of 'business' with zero interest other than profits can sell any malicious technology and lobby for it. Everything has consequences, and unintended consequences, most of these principles are lessons learned over hundreds of years and it will be tragic to let petty self interest continue to dilute and diminish them.
