It depends what you want to do. Deep Learning is pretty much to be Python, but 3D Reconstruction is almost exclusively C++.

If you want to do robotics, do you want to do Deep Learning for robotics, or do you want to do 3DR? Same question for medical imagine.

Also is what you want to work on run in a cloud service like GCP, or is it run on device? If it’s run on device there’s like 100% change it’s C++.

My plan is to know both.
