summary

Now new technologies are emerging , If every time a new technology comes out , If we all go deep into it , It's easy to distract . New technology may be a long time before we can use it in our work , When the new technology learned can not be applied , It's easy for us to forget , In the end, when it really needs to be used , And start all over again （ Although it's faster to get started ）.

I think as a technical person , We should embrace new technology , When you enter this industry, you should know that it's never too late to learn , So in the face of new technology , Don't contradict , Just embrace change .
