Yes the software field is and will be the best in the future. We cannot deny technology as it is a major part in our life. The graph of the software field will never go down . But you may know that mostly all the people want to learn technology. The job availability is less  as compared to others now as more and more people are getting involved in  this field . You have to be at least good in this field , who knows how to write codes and have problem solving skills and proper knowledge due to which your state will be defined in a company. So it is best now and for future too it will be good .
