The AI Act, first proposed in 2021, will govern any product or service that uses an artificial intelligence system. The act will classify AI systems according to four levels of risk, from minimal to unacceptable. That means some AI uses are an absolute no-no, such as “social scoring” systems that judge people based on their behavior. The technology scans passers-by and uses AI to match their faces to a database. The EU’s executive arm says most AI systems, such as video games or spam filters, fall into the low- or no-risk category.
