Fireship - 7 Programming Myths that waste your time
The speaker reflects on their programming career, realizing much of their work was unproductive due to chasing trends and adhering to rigid programming dogmas. They debunk nine myths that waste programmers' time, such as the need to use the latest technology to stay relevant, the belief in one true way to write code, and the pursuit of 100% test coverage. The speaker argues that many real-world systems still rely on older technologies like WordPress, PHP, and Java, and that focusing on these can be more beneficial for employability. They also caution against over-optimizing code and infrastructure prematurely, as well as relying too heavily on AI tools, which can lead to inefficiencies. Instead, they advocate for building a strong foundation in problem-solving and understanding the underlying principles of coding, which can be achieved through resources like Brilliant.org.
Key Points:
- Focus on practical skills and real-world technologies like PHP and Java for better employability.
- Avoid chasing the latest tech trends; many systems still use older, reliable technologies.
- Don't adhere strictly to programming dogmas; use a mix of paradigms that work best for your needs.
- Quality over quantity in test coverage; 100% coverage doesn't guarantee high-quality code.
- Use AI tools wisely; they can boost productivity but also lead to inefficiencies if over-relied upon.

3. 🌐 Tech Relevance and Dinosaur Technologies
- Older technologies like WordPress, PHP, Java, SQL, and C++ remain dominant across many sectors.
- WordPress and PHP are still widely used for web applications, indicating their lasting impact.
- Java continues to be a staple in enterprise solutions, showing its entrenched position in the industry.
- SQL databases are still the norm, underscoring the continued reliance on these systems.
- C++ is crucial for low-level systems, highlighting its enduring importance.
- While new technologies like Nex.js, Kotlin, NoSQL, and Rust are emerging, the majority of tech jobs still require proficiency in these older technologies.
- The perception that only the latest technologies are relevant is a myth; older technologies are still in high demand.
- New technologies are gaining traction but have not yet surpassed the widespread application of older technologies.
4. ⚠️ Risks of Early Tech Adoption
- Critical banking systems continue to rely on older technologies such as Cobalt, indicating a reluctance to shift from established systems that still function effectively.
- Despite advancements, Java will continue to power 3 billion devices in the foreseeable future, highlighting the enduring presence of legacy technologies.
- Many CTOs maintain the philosophy 'if it ain't broke, don't fix it,' suggesting a cautious approach to adopting new technologies.
- Twitter engineers launched a promising database called Fauna, which, despite initial potential and support, failed as a business, emphasizing the risks of investing in new, unproven technologies.
- Early adopters of Fauna faced significant setbacks when the business failed, underlining the potential downsides of adopting proprietary technologies without guaranteed longevity.
- A case study of Fauna shows that despite technological promise, market viability and business sustainability are critical, as failure can lead to significant financial and operational setbacks for early adopters.
- The continued reliance on Java and Cobalt in banking underscores the importance of stability and reliability in critical systems, where the cost of failure can be high.
5. 🤔 Programming Dogma and Flexibility
- Strict adherence to programming dogma can result in wasted time, as multiple solutions often exist for a given problem.
- Programming 'cults' like object-oriented and functional programming offer educational benefits but can be limiting if followed exclusively.
- JavaScript exemplifies a multi-paradigm language, allowing the effective integration of different programming styles.
- The functional programming renaissance in 2018 discouraged class usage, but practical experience highlights their utility.
- A balanced approach, combining functional and object-oriented principles, can enhance coding practices.
- For instance, using JavaScript's flexibility, developers can apply functional programming for data manipulation and object-oriented principles for structuring applications, achieving a balanced and efficient coding practice.
6. 📚 Clean Code Missteps
- Clean code practices, as advocated by Uncle Bob Martin, emphasize meaningful naming, small functions, and consistent formatting. These principles aim to enhance code readability and maintainability.
- While the DRY principle (Don't Repeat Yourself) suggests avoiding code duplication, strict adherence can lead to overly complex and unnecessary structures, which may increase technical debt.
- An overemphasis on clean code can result in developers spending more time refactoring than developing new features, leading to 'paralysis by analysis.' This can hinder project progress and innovation.
- A pragmatic approach is 'RUG' (Repeat Until Good): initially duplicate code and refactor into a single abstraction only when it provides clear benefits. This approach balances initial development speed with long-term maintainability.
- For example, in a real-world scenario, a development team excessively focused on DRY principles may create complex inheritance hierarchies that are difficult to understand and maintain, slowing down development.
7. 🔍 The Myth of Test Coverage
- 100% test coverage is a myth for code protection; high coverage does not equal high quality.
- Optimizing for 100% coverage can waste time and be misleading, as it encourages writing tests that touch lines without catching real bugs.
- High coverage gives a false sense of security and can slow down CI builds, increasing costs.
- Focus on test quality rather than quantity to ensure effective code testing.
- Examples include scenarios where high test coverage didn't prevent bugs, highlighting the importance of targeted testing strategies.
- Common misconceptions are that more coverage equates to fewer bugs, which is false without considering test quality.
- Counterarguments suggest that targeted tests for critical paths are more efficient than aiming for high overall coverage.
8. 🚀 Performance Optimization Myths
- It's a myth that you should always optimize for performance; focus on correctness first.
- Benchmarking and optimizing code without scale justification is a time waster.
- Optimize for performance only when production issues become obvious.
- Complex cloud infrastructure isn't necessary unless scaling like major companies; a simple VPS may suffice.
9. 🤖 AI in Programming: Friend or Foe?
- AI tools like Claude Sonnet 3.7 excel at writing code but often produce verbose results, potentially creating unnecessary complexity, such as developing new JavaScript frameworks from scratch when not needed.
- Over-reliance on AI tools can lead programmers to lose touch with their coding skills, approving AI-generated code without fully understanding it.
- AI programming tools can significantly boost productivity but may also waste time if used improperly, highlighting the importance of balanced and informed usage.
