Tell me something important about IT that I don't know

[ghking]

I am a geek, I have learned so many Techlonogy, But I still think there is something important that I don't know. So try tell me something important that I don't know.

It should be related to IT, here is part of what I have studied:

hardware: Digital and Analog Electricit | PCB | FPGA | DSP | MCU | CPU-architecture

software: compiler | LLVM | operating system | linux | cloud-computing | Virtualization | Container

language: verilog/systemC | C/C++ | Python | java | javascript | haskell | lisp | function-language | logic-language | ... (needn't recommand anymore, It's enough)

web : front-end | back-end | react | spring | nodejs | koa | ... (needn't recommand anymore, It's enough)

other : algorithm | design patterns | software engineering | Artificial intelligence | big-data | Continuous integration | devops

Consider the ethical side of IT: https://www.gnu.org/philosophy/free-sw.html.

It's a good ideal, but it's just a mode of presentation of software.

Thank you, I've done some work on this before, OMG has some standard for it. But I am not good at it, It's really a good direction. Thank you very much.

Focus more on the real problems over tools.

I have try to control myself, but It's really hard. As a Perfectionist, I really cann't.

Why not just research something you don't know much about? Like how embedded computers interface with a car.

It may just open another pandora's box for me.
