🔧 When you might need Assembly in 2025:
Embedded Systems & Microcontrollers

Writing firmware for devices like Arduino, STM32, or custom chips.

Sometimes performance or size constraints require Assembly-level tweaks.

Operating Systems, Bootloaders, or Compilers

Low-level dev (e.g., writing a kernel or BIOS) still involves Assembly, especially x86 or ARM.

You’ll often write just a few lines of Assembly to interface with hardware or switch CPU modes.

Reverse Engineering / Security / Hacking

If you're doing malware analysis, exploit development, or binary patching, Assembly (especially disassembly) is a must-have skill.

High-Performance Computing / Game Engines (rare)

In very rare cases, you might use SIMD instructions or hand-tune Assembly for extreme performance — but most of this is abstracted by compilers or libraries.

❌ When you don’t need Assembly:
Web dev, mobile apps, backend services, machine learning, game dev (Unity/Unreal) — basically anything high-level.

Modern languages like Rust, Go, C++, or even C compile efficiently, and the compiler usually does a better job optimizing than humans.

Even embedded development often uses C with just small bits of inline Assembly if absolutely necessary.

🧠 Should you still learn the basics?
Yes — even in 2025, it’s super valuable to understand what Assembly is and how it works, because:

It makes you a better programmer (you understand how code turns into CPU instructions).

It helps with debugging weird bugs, crashes, or performance issues.

It’s a great tool for interviews, especially for low-level or systems roles.

Simply yeah !

Hey! ^-^
In short, Assembly is no longer a requirement for most software engineers in 2025 — but in some (!!!) specialized domains, it remains irreplaceable.

Yes, if:

• You work (!!!) in embedded systems, firmware, or device driver development where hardware-level control is required.
• You're developing performance-critical routines (e.g., cryptography, game engines, signal processing) where C/C++ alone is not enough (but actually in 100% of cases is enough).
• You're reverse engineering software.

No, if:

• You’re primarily developing web, mobile, or desktop applications using high-level languages (e.g., JavaScript, Python, Java).
• You don’t need fine-grained control over memory, CPU instructions, or timing.
• You prioritize development speed, maintainability, and cross-platform compatibility over absolute performance.

probably yea

You can learn Assembly in 2025, but you don’t need it for most development work. Assembly is still used in a few areas like embedded systems, low-level optimization, OS kernels, reverse engineering, security research, and performance-critical code, but for general software development, modern languages and compilers handle almost everything for you.

That said, understanding a bit of Assembly can help you reason about what’s happening under the hood, debug tricky issues, or write more optimized code. So it’s not required, but it can definitely be valuable depending on what you’re working on.

From a Student Developer's Perspective

As someone who's actually written Assembly code (x86 and ARM) for projects, here's my honest take:

Short Answer: Probably not "need", but definitely valuable

When I've Actually Used Assembly:

1. Understanding How Code Really Works
Learning Assembly helped me understand what happens when I write int x = 10; in C or Python. It's like learning how a car engine works - you don't need to know to drive, but it makes you a much better driver.

2. Debugging Weird Issues
When my Android app crashed with a cryptic native error, knowing how to read stack traces and disassembly helped me figure out what was actually happening. High-level debugging tools don't always tell the full story.

3. Performance Optimization (Rarely)
For game development or performance-critical code, sometimes understanding the assembly output helps you write better C/C++ code. But honestly, modern compilers are usually smarter than us.

Real-World Scenarios Where You Might Need It:

• Embedded Systems/IoT: If you're programming microcontrollers (Arduino, ESP32, STM32), you'll occasionally write inline Assembly
• Operating System Development: Building a bootloader or kernel requires at least basic Assembly
• Reverse Engineering: If you're interested in security, malware analysis, or modding games, Assembly is essential
• Competitive Programming: Understanding how your code compiles can help optimize for speed contests
• Game Engine Development: Low-level graphics programming sometimes needs SIMD instructions

When You DON'T Need It:

• Web development (frontend/backend)
• Mobile app development (Java/Kotlin/Swift)
• Data science/Machine learning
• Most enterprise software
• Game development with engines like Unity/Unreal

My Recommendation:

Learn the basics - spend a weekend understanding:

• How registers work
• How the stack works
• How functions are called
• How if/else and loops translate to jumps

You don't need to become an Assembly expert, but understanding the fundamentals will make you a significantly better programmer. It's helped me:

• Write more efficient code
• Understand memory better
• Debug native crashes
• Appreciate what compilers do for us

Think of Assembly like learning manual transmission - most cars are automatic now, but knowing how it works makes you a more skilled driver.

Practical Learning Path:

1. Learn basic x86-64 or ARM assembly syntax
2. Write simple programs (calculator, loops)
3. Look at compiler output of your C/C++ code
4. Try writing a tiny bootloader or OS kernel stub

Bottom line: You probably won't write much Assembly in 2025, but understanding it is still incredibly valuable for any systems-level work or when you need to understand what's really happening "under the hood."

You don’t need Assembly for most software development in 2025 — but it remains important in a few specialized areas where hardware-level control or performance matters.

[ayoub0029]

Short answer:
Most developers won’t ever need Assembly today. High-level languages and modern compilers already handle low-level details for you.

Still, in some cases:
Assembly matters in areas like embedded programming, kernel/driver development, reverse engineering, and situations where every bit of performance counts.

In summary:
You won’t be writing Assembly regularly, but having a basic understanding of it helps you debug tricky issues and better grasp how your code really runs underneath.

It depends on your career decisions, if you are kind of a guy who's into hardware programming you need assembly for sure but if you are not into hardware related stuff, feel free not to go for assembly.
