Nobel Prize winner Demis Hassabis just accidentally revealed who survives the next 5 years and who doesn't.
"One person who understands AI will outperform an entire startup team"
Most founders heard that and thought: "Oh no, I need to learn prompt engineering"
Wrong.
That's not what "understands AI" means anymore.
It means: building workflows. Chaining systems. Automating entire departments.
Not typing better questions into ChatGPT.
The split is brutal:
> 90% of people = still using AI like a calculator
> 10% of people = treating it like infrastructure
In 5 years, the 10% will run everything with half the headcount.
The 90%? Replaceable.
Which group are you in?
Watch the full breakdown. This is the only skill gap that actually matters right now.

So when people ask me for book recommendations, I don't give the same ones as others: Clean Code, The Pragmatic Programmer, and DDIA. Those are fine, of course, but you've heard about them many times.
In the new issue of Tech World With Milan newsletter, there is the list I actually gave people in 2026. 17 books, sorted by the problem you're having.
A few that earned their place:
- ๐ ๐ฃ๐ต๐ถ๐น๐ผ๐๐ผ๐ฝ๐ต๐ ๐ผ๐ณ ๐ฆ๐ผ๐ณ๐๐๐ฎ๐ฟ๐ฒ ๐๐ฒ๐๐ถ๐ด๐ป by @JohnOusterhout. I read it late and wished I hadn't waited. Best explanation I know of why complexity is in and how to push back.
- ๐๐ฒ๐๐ถ๐ด๐ป๐ถ๐ป๐ด ๐๐ฎ๐๐ฎ-๐๐ป๐๐ฒ๐ป๐๐ถ๐๐ฒ ๐๐ฝ๐ฝ๐น๐ถ๐ฐ๐ฎ๐๐ถ๐ผ๐ป๐, 2nd edition, by @martinkl and @criccomini. The rewrite adds AI data systems. Still, the book I reach for most on distributed data.
- ๐๐ ๐๐ป๐ด๐ถ๐ป๐ฒ๐ฒ๐ฟ๐ถ๐ป๐ด, by @chipro. If you're putting LLMs into production, this is the one.
- ๐ง๐ต๐ฒ ๐ฆ๐ผ๐ณ๐๐๐ฎ๐ฟ๐ฒ ๐๐ป๐ด๐ถ๐ป๐ฒ๐ฒ๐ฟ'๐ ๐๐๐ถ๐ฑ๐ฒ๐ฏ๐ผ๐ผ๐ธ, by @GergelyOrosz. The career stuff nobody teaches you. We usually learn it by experience the hard way.
- ๐ฅ๐ฒ๐ณ๐ฎ๐ฐ๐๐ผ๐ฟ๐ถ๐ป๐ด, by @martinfowler. Changing code without breaking it, which is most of the actual job.
My own book is on the list too. ๐๐ฎ๐๐ ๐ผ๐ณ ๐ฆ๐ผ๐ณ๐๐๐ฎ๐ฟ๐ฒ ๐๐ป๐ด๐ถ๐ป๐ฒ๐ฒ๐ฟ๐ถ๐ป๐ด: 63+ laws and principles every engineer learns from experience and fails. I collected them so you don't have to.

Flutter Devs, this is the smoothest button tap effect widget you'll ever have.
Why smoothest? It uses spring physics and reacts soo natural to touches.

THE CO-FOUNDER OF GITHUB GAVE A 46-MINUTE TALK ON GIT BECAUSE ENGINEERS WITH 10 YEARS IN HAVE NEVER SEEN HALF OF WHAT IT DOES
This is Scott Chacon. He wrote Pro Git -- the book most devs secretly learned Git from and he co-founded GitHub. So when he says you're missing things, you're missing things.
About ten minutes in it clicks: half the "git disasters" you've ever fixed by deleting the folder and re-cloning had a one-line solution sitting in the tool the whole time.
Git ships new code almost every day -> roughly nine commits a day for over a decade. Most of us stopped learning it the second we memorized add, commit, push.
Knowing Git isn't a senior-dev flex anymore -> it's the floor. The agent writes the code now. Your real job is reading, branching, and untangling the history it leaves behind.
The day an AI agent force-pushes over your main branch, these 46 minutes are the difference between a quiet fix and a very loud apology.
Save it now.
You'll reach for it sooner than you'd like โ
Most tech content is noise. But one YouTube channel is quietly archiving the deepest engineering knowledge on the internet.
Iโve been watching Ryan Petermanโs (@ryanlpeterman) podcasts over the last few months, and the signal-to-noise ratio is absolutely insane. He is sitting down with:
โช๏ธ Turing Award winners (like Leslie Lamport & Mike Stonebraker)
โช๏ธ Bjarne Stroustrup (Creator of C++)
โช๏ธ Elite Big Tech ICs & VPs of Engineering
This isn't just about writing code.
They dive deep into the reality of high-level tech careers : foundational architecture, system design from first principles, and complex trade-offs like Paxos vs. Raft.
If you are serious about computer science, bookmark his channel.
It's the masterclass you won't get in a classroom.
Anthropic's head of security:
"90% of our code is written by Claude. If yours is too and nobody's reviewing it, you're shipping bugs you'll never notice."
In 28 minutes he shows the exact security setup Anthropic uses internally to protect their own projects.

a professor at Illinois got frustrated with existing systems programming textbooks
so he started a wikibook project and had students help write it
it covers C, processes, threads, synchronization, memory allocation, networking, filesystems, scheduling and security
all in one free PDF
it eventually became the official textbook for CS 241 at UIUC with more than 1000 students taking the course every year
written for people who already know how to code and want to understand what actually happens underneath
