You Can’t Write Perfect Software. Did that hurt? It shouldn’t. Accept it as an axiom of life. Embrace it. Celebrate it. Because perfect software doesn’t exist. No one in the brief history of computing has ever written a piece of perfect software. It’s unlikely that you’ll be the first. And unless you accept this as a fact, you’ll end up wasting time and energy chasing an impossible dream.

Foreword

A host of the timid avails not in war — One warrior man is better than a hundred thousand.

Andrew Ng — founder of DeepLearning.AI and co-founder of Google Brain — has a clear yet challenging message for software developers watching the world of AI:

“AI won’t replace software developers, but software developers who use AI will replace those who don’t. The future of coding is a symphony between human problem-solving and AI’s capacity to execute it quickly. Your core value shifts from writing code to architecture, debugging, and — most importantly — directing intelligent assistants. Learn to speak the language of AI, and you’ll become a 10x-more-powerful engineer.”

The following are excerpts from Andrew Ng’s talk titled “From Code to Product in Hours — The New Reality of AI Development,” some of the key points of which I’ve captured below.

Discussion: Andrew Ng’s key points for developers

In this conversation, Ng explains the practical skills, philosophical shifts, and emerging bottlenecks that developers need to know in order to stay at the front line. The text below is a free interpretation of his remarks.

1) Focus and a new look at speed

Speed is the single biggest predictor of success for innovative projects. AI is the driver of that speed: it makes building prototypes and small standalone products 10× faster, and it increases the speed of producing final, ready-to-use products by about 50%.

2) A new philosophy of software

The new motto of smart teams is “move fast and be responsible.” It means that prototypes are built very quickly in a safe, isolated environment, and then safety and security are added to the selected, scalable ones.

3) Code as an artifact (output)

Because AI can write code, code as an output becomes less valuable. This makes important decisions — such as architecture or database design — more like a “two-way door” (i.e. reversible; in other words, decisions that, if wrong, can be easily corrected). This capability enables more iteration, and even rebuilding from scratch.

4) The new bottleneck

As building software becomes easier, deciding what to build becomes the biggest bottleneck. Ng calls this the “product management bottleneck.”

5) Honing your intuition

Developers should work to develop and sharpen their intuition and inner judgment, drawing on users to make decisions about products. The goal of collecting user data is to train the way you judge — not merely to use it to make a decision in one specific case.

6) Learning to code

The advice that people shouldn’t learn to code because AI will automate it is “one of the worst pieces of career advice in history.” Every step of automation (from assembly to higher-level languages to AI) has made coding more valuable and more accessible.

7) Essential skills in the future

The most important skill in the future is being able to tell a computer exactly what you want it to do. Knowing the language of the computer and coding provides a deeper understanding for more precise control of AI tools.

8) The role of the AI Engineer

We are facing a shortage of “AI Engineers.” The skills required for this emerging role include: familiarity with AI-assisted coding, expertise in AI building blocks (including RAG and agent workflows), rapid prototyping skills (including basic full-stack knowledge), and basic product-management skills and user judgment.

9) Rapid Engineering

Andrew Ng prefers the term “Rapid Engineering” over “vibe coding.” He describes the process of working with AI coding assistants as a “deeply intellectual exercise,” not merely relying on “vibes.”

Excerpt: None.

I read the book The Psychology of Money: Timeless lessons on wealth, greed, and happiness alongside a few of my dear friends.

In this book, Morgan Housel examines how people think about, manage, and deal with money. Rather than emphasizing technical aspects, the author explores the behavioral and emotional sides of human beings. Drawing on psychology, historical facts, and personal experiences, he attempts to show that financial success depends more on human behavior, attitudes, and personal values than on intelligence or technical knowledge.

In this book, you won’t find any signs of ready-made solutions or technical and financial advice. My experience reading this book consisted of “learning the core of important problems,” “understanding the dimensions of the issue, especially from a psychological perspective,” and “having my beliefs and past learnings challenged.”

Without giving away any spoilers, let’s look at a few examples together:

• The book explains that being “rich” is different from being “wealthy,” and what you should actually strive for is wealth!
• Elsewhere, the book explains a concept called “enough,” emphasizing that what constitutes “enough” is entirely personal. It then explores how this concept can be used to achieve “financial freedom.”
• In another section, the book warns you to watch out for the “You vs. Me” trap. When investment advisors—whether amateur or professional—give advice, they usually have their own circumstances or a specific type of investor in mind. You must be careful, as your situation might be completely different from the people these advisors are targeting.

The Psychology of Money is one of those books that you should re-read every once in a while. More importantly, you can hold discussion and brainstorming sessions for every single chapter, which will undoubtedly spark engaging debates ;).

I am grateful to my dear friends who initiated and gave me the perfect excuse to read this valuable book.
