The higher up you are there are so many layers of abstraction that you need to rely on. To get good performance there are so many layers that can be a bottle neck.

When you are doing low level stuff it can be liberating because you don’t have to rely on so many abstractions.

I find most of programming dealing with bad abstractions or choosing a library/language that does 90% of what you want but the final 10% is extremely difficult or requires you to abandon some library/language and start from scratch.
