Guys, I think I finally understand when and how to use pointers! Have avoided them for years, but now couldn't escape it.

Someone way smarter than me:

My current understanding is that it is best to use pointers when you don't want to actually pass the object/value around if it is very large, particularly in situations where you may need to access a small piece or perform mutations on it.

Happy to be wrong, as long as I learn.

Thanks! 

I started my hacking career with C++ and point clouds. Genuinely was a lost puppy at the time, went way too advanced too quickly. Basically beat my head against documentation and googling. 

I’ve had trauma since then with pointers, and finally came to junction where I couldn’t avoid. Haha

Yup pointers are great for zero copy transfer of data

By the way, whenever you run any python thread by default it dynamically allocates memory regardless of whether you’ve previously had it before or not, hence pointers
