Information security or low-level programming (drivers, operating systems, etc.)?

Question

Career in IT

Good day.
I can't decide on a direction.
Interesting development at a low level (operating system drivers, etc.), as well as information security.
I would like to see the features of these areas from people who have had experience in it. What do you like, what is interesting, what attracted you, etc.
Since I did not delve deeply into any of the areas, I would like to know the details of work in these areas, both positive and negative.
I apologize if the question seemed stupid to you.
Thanks in advance.

Answer 1

Open the headhunter and you will see that no skilled drivers are needed, and the security guards are learning GOSTs, rubbish alone

Answer 2

Drivers all over the world are written by units.
