SMART CITIES, LIKE many things, took a beating in 2020. Alphabet, Google's parent company, pulled its Sidewalk Labs subsidiary out of a smart-city project in Toronto. Cisco killed its plans to sell smart-city technology. And in many places, city budgets will be affected for years to come by the pan-demic's economic shock, making it more difficult to justify smart-city expenses.

与许多事情一样，智慧城市在 2020 年遭受了打击。谷歌母公司 Alphabet 将其子公司 Sidewalk Labs 撤出了多伦多的一个智慧城市项目。思科取消了销售智慧城市技术的计划。在许多地方，城市预算将在未来几年受到大流行病经济冲击的影响，从而更难以证明智慧城市支出的合理性。
