Dear Aspirant,

If your friend is into science and inventions and by cse you means computer science and engineering then he is making the best decision of his life by going into the most popular and one of the best field of engineering.

There is a very famous quote from satya nadela " we are living in a software world". And hence the world is undoubtedly heading towards the cse and its application is evident in almost every industry. I think you should suggest him that he should keep going and learn new and innovative things in this field.

Feel free to comment you doubts, if any.

Hope this helps. Thank you.
