become the surfer.

Opening roadmap
The AI shift is already changing how people build, learn, and get hired. Today is about how to ride it on purpose.
Today's route
1
See the Wave
AI landscape, salary reality, and why the old playbook broke.
2
My First Wave
What shipping for 5M users at Wrtn taught me.
3
The Next Wave
Physical AI, research bets, and why robotics matters now.

Your Surfboard
A blunt career guide you can act on this week.
The fastest growth in history
ChatGPT reached 200 million users in two years.
Now software developers sit at 8–9/10 on AI job exposure.
The surprising part is not that AI is coming. It is that the most screen-native, high-paying work is now directly in the blast radius.
Karpathy's warning
8–9 / 10
Developers rank near the top of AI exposure because their work already happens in language and interfaces.
Why it matters
AI Researcher
$160K - $400K TC
Publish papers, advance SOTA.
Deep math & experimentation.
AI Engineer
$180K - $320K TC
Build production ML systems.
High demand, model serving, infra.
Data Scientist
$130K - $250K TC
Analyze, model, interpret data.
Bridges research and product.
AI Product Manager
$150K - $280K TC
Define what to build and why.
Rarest combo of user & tech.
Salary reality check
That mismatch is exactly why the window matters: the Korean premium is still small, but the capability demand is moving much faster than the salary signal.
United States
AI engineers already command a visible compensation premium.
Korea
Only a modest gap today, which means the upside is more about timing than current salary.

6.1%
CS grad unemployment rate
Degree holders can't land jobs. Skills mismatch — market wants AI-augmented builders.
75% of programming tasks are coverable by AI · 14% hiring slowdown for traditional coders. The old playbook is broken.
What students think matters
These signals are not meaningless.
They just no longer win by themselves.
What recruiters actually want
The strongest signal is still simple:
can you point to real things you built?
The ChatGPT moment for robotics
When machines begin to understand, reason, and act in the real world — that's Physical AI.

The 12-month paradigm shift
A year ago the story was “let AI write it.” By 2026 the job is managing agents, systems, and feedback loops.
Feb 2025
“Vibe Coding”
Prompt the model, let it write, and optimize for speed and vibes. Great for momentum. Weak for sustained complexity.
→
12 months
Early 2026
“Agentic Engineering”
Break work into systems, orchestrate agents, verify outputs, and keep humans focused on judgment and design.
Jensen, Jul 2025: “Study physical sciences, not software engineering.” The winning stack is fundamentals + orchestration + domain expertise.
Two waves I caught
Transition
I caught a product wave and a research wave. Different contexts. Same truth: define the right problem first.
Why this section matters
Wave one
Wrtn — shipping fast, owning user outcomes, and learning what actually drives retention.
Wave two
WoRV — building systems that move from benchmarks to robots in the real world.
Throughline
Product judgment + research depth is the combination that compounds.
Part 2 · Product wave
Section divider
Riding the product wave at Wrtn —
how I helped build a 5M-user AI agent.
Why this section matters
Mode
Move fast, ship weekly, and feel user feedback immediately.
What to watch
Execution speed, product taste, and how small technical choices hit real retention.
Part 2 · My first wave
Your Own AI — the AI that's just yours. I joined when the wave was still forming and ended up owning product work end-to-end.
My role
AI Engineer — end-to-end product ownership

Life at a startup
At a consumer AI startup, the work loop is brutally simple: ship, get surprised, recover fast, and ship again.

Neither is "better." Pick the wave that matches your surfing style.
Product wave takeaway
The 5M users came from
problem definition, not prettier algorithms.
When the user problem is clear, the stack becomes simpler, faster, and more valuable.
Part 3 · Physical AI
Section divider
From game data to real robots. From 29% to 97.3%.
Why this section matters
Why now
Physical AI is leaving the lab and becoming an economic platform shift.
What this section shows
How research moves from simulations, to benchmarks, to robots that actually work.

Part 3 · Mindset
🔬Define the research question and the success metric before you touch implementation.
⚡Build the simplest version that could work, then iterate with evidence.
📦A paper without code, or a model without deployment, is only half-finished.
Research wave takeaway
Research still wins when it solves a real problem.
Benchmarks matter, but only when they change what becomes possible in the world outside the paper.
Part 4 · Career guide
Section divider
The blunt truth about what you need
to ride this wave — and what matters
far less than students think.

"If your GitHub only has homework, you're competing with everyone else who also did the homework."
Class assignments prove you followed instructions. Personal projects prove you can think. Recruiters know the difference.
Empty — only homework
Active — real projects
What to build this month
You do not need ten ideas. You need one concrete thing that looks real, runs publicly, and teaches you something hard.
Rule of thumb
A project should be understandable in 30 seconds and defensible in a 10-minute conversation.
Beginner
Personal dashboard
A polished utility with live data and a deployed URL.
Intermediate
Agent harness
A multi-agent orchestrator that plans, acts, and reports.
Advanced
Open source CLI
Solve a real pain point and publish something others can install.

Year-by-year roadmap
Do not try to do all four years at once. Each stage has one main job. Nail that job, then move on.
Year 1
Explore
Master fundamentals in Python, math, and basic AI.
Get curious fast about what kind of wave you want to ride.
Year 2
Build
Start projects and use AI tools aggressively.
Ship your first real code instead of collecting tutorials.
Year 3
Ship & Intern
Target internships and public contributions.
Make your portfolio legible to a recruiter in 30 seconds.
Year 4
Optimize
Polish the strongest work and tailor for target roles.
Land the role with focused applications and proof of shipping.
Part 4 · Practical
Your next job usually comes from someone you've helped, not someone you've merely introduced yourself to.

Part 5 · Action Items
You've seen the wave. You've seen the surfboard.
Now get in the water.
Yes, it costs money. Check student support programs. Anthropic and Cursor both have options. This is the most important investment you'll make this year.
Claude Code
Terminal AI agent
Cursor
AI-native VS Code fork
Think of one daily frustration. Something that wastes your time. Build something that fixes it. Let Claude init the project for you.
$ claude "init a project that solves X"
✓ Scaffolding project... creating README, setting up repo, drafting first feature...
→ Let AI help you start. You provide the problem. It provides the momentum.
Final step
Make AI part of your default workflow — not a toy you only open when homework is due.
📅
Schedule planning
Turn vague to-dos into a real plan.
✉️
Email drafting
Write faster without sending careless messages.
💻
Code review
Check ideas, diffs, and bug hypotheses on the go.
📚

The surfer's choice
Sam Altman, August 2025: “If I were graduating college right now, I'd feel like the luckiest kid in all of history.” Luck only matters if you act on it.
The wave doesn't care

It's coming either way.

you'll do this week.
Right now. On your phone.
I'll wait.
