I think it is important, because every profession is important, and although machines may replace humans, there will always be things that machines cannot do. But these machines can bring some benefits to people, such as medical treatment, the development of machines can help us detect more diseases, and also help us treat more diseases. And I have a case, when the astronauts return to the earth, they need to calculate the landing site of the astronauts, and in a calculation, the computer calculated the wrong landing site, then the computer needs to calculate. All of these industries are irreplaceable and important.
