1151．Do We Really Need Smart Cities？
Cities around the world are racing to become "smart".It's just like a classroom full of hard-working students.Take Toronto，Canada，for example.Technology （Tech） company Google has made a 1，500-page plan.It's going to remake two neighborhoods with things like snow-melting （融雪的） roads.
To build smart cities，we need lots of new technologies，such as robots and artificial intelligence （AI）.These technologies will lead to safer and more efficient cities.However，they will also raise questions about privacy （隱私）.
But there is a more serious problem：Smart cities will be difficult to manage.
As we know all too well from our personal lives，sometimes tech products are not dependable.The Internet and our computers break down regularly.Tech products also age quickly.Only a few years into their lives，problems may become more and more common.
In smart cities，many basic systems and services，such as water services，are based on such tech products.What if they break down regularly？Can you imagine the result？
New technologies in 2020 will be outdated before 2025.If we use smart technologies widely in cities，we will need to be prepared to replace them every few years.But who would want to pay this bill？
The most important problem is whether having a smart city will make us better at solving city problems.Smart technologies can't solve problems on their own.Suppose AI programs discover a road that needs to be repaired.It still requires people to do the job，doesn't it？
As an engineer，I think smart technologies should have a place in cities.However，that place is not everywhere.For many of our city problems，we don't really need the latest technologies.The best of the old ideas work better.
