In a packed room at City Hall on Monday, Council Member James Vacca heard testimony from city officials, technologists, and civil rights advocates on his proposed legislation for transparency in the use of algorithms for city services. Vacca said that the legislation is, to the best of his knowledge, the first of its kind in the United States. Although most of the testimony was in favor of the proposed legislation, the hearing revealed a schism between the tech community as represented by the trade nonprofit Tech.NYC—whose dozens of members include giants like Facebook and Google, as well as smaller companies like Meetup and Civic Hall—and the technologists who testified as individuals.
