Artificial intelligence is being increasingly used by governments for surveillance through tools like facial recognition, smart cities, and policing. Over 75 countries use AI for surveillance, with China having the largest implementation that collects facial data from cameras. AI is also impacting economies by automating many jobs and potentially exacerbating wealth inequality. It could create new jobs but may replace workers and reduce tax revenue. The future effects of AI are uncertain but it is rapidly transforming society and influencing various industries and how we interact with technology. Governments are also using social media data and personality profiles to target political ads and influence elections.
