I have interest in physics maths i have not studied computers since my 9 grade i donot have interest in coding neither in future i see myself working on copmuters but rather on machines research projects like in drdo but seeing future opportunities confused which to take cs or mechanical.
I will suggest you to take Mechanical, if you are not quite sure of excellence in coding. Coding and Software Development are fundamentals of any CS Engineer, be it in fields of Technical Architecture or Web and Software Development.
Core Prospects of Mechanical
Research Organizations : BARC ISRO DRDO
Operations Industries : ITC Reliance Unilever etc.
Mechanical Plants : Tata Steel Tata Motors TVS etc.
Digital/Technological Prospects in Mechanical
Artificial Intelligence and ML in Operations
Computer Integrated Manufacturing
Automation and Self Driving Cars
Robotics and UAVs.
