I summarized the most important lessons I learned after making over a dozen career moves, along with a simple framework to evaluate whether it is the time to stay in my current role or start looking for a new one.

Newton would publish his Philosophiæ Naturalis Principia Mathematica, the foundation of Newtonian physics, much later, in 1687.
Newton credited Jean Picard for his contribution.
Picard relied on the works of Italian astronomer Giovanni Battista Riccioli to design his experiments.
Riccioli, along with his colleague, Francesco Maria Grimaldi, was also the first to perform the first experiments to measure acceleration of failing bodies.
...between the distances of center of the Moon and the distance of Earth's surface from Earth's center fit his formula of gravitational force being proportional to the inverse square of that ratio.
Studying the history of scientific facts.
Earth's true size was not known until the 1670s, when French Astronomer Jean Picard measured it precisely using triangulation.

Ranked contribution ladders solve this.
Contributors have to climb the ladder with smaller contributions. After positive contributions they are allowed to send increasingly large PRs.
Also, nothing stopping one from throwing the slop grenade back with AI-generated comments.
Lazy work used to mean too little output.
Now, with AI, it often means too much and more work for everyone else.
@tobi call it "slop grenades."
A "Slop Grenade" is when you let AI produce the work and pass it on without adding any value (including checking it).
Someone else has to wade through it, catch the mistakes, and clean up the mess.
You save time and look productive but someone else pays for it.
I can't stop watching this.
Finally.
🚨Mikel Arteta tried to hug the referee but was given a yellow card xitter.cf/fbtl_topcee/status/209…
Einstein's views on reality and abstractions should be mandatory reading for AI researchers trying to build world models.
From "Physics and Reality".
(Still in awe about this being a mere introductory paragraph in an essay about relativity and quantum mechanics.)
Took me 13 years to finally complete watching Attack on Titan.
Admittedly not an anime connoisseur, but what a masterpiece.
Anything else close?
If I see "not x, not y, but z" I stop reading.
Guaranteed AI slop.
Not because it is artificial, not because it overuses an otherwise interesting writing style, but because it is usually trying to frame a bland argument as insight.
Everyone wants to contribute code.
Fewer want to integrate into team operations, task coordination, testing, migration, maintenance, operations, on call.
Writing the code is, by large, the fun part of the work.
Volunteering only to do the fun part is ... a choice.
Growth papers over a lot of bad business cases.
Lack of growth highlights all that is wrong with broken business cases.
That also works with society.
That also works with life.
The universe demands growth.
I wonder how much of the "programming is dead" discourse is the result of people who never worked on production system being able to create prototypes.
I can ask ChatGPT for good medical opinions all day and still would not think I can handle a general population of patients.
Using "coding" and "engineering" interchangeably does not help the discourse.
An AI writing code has no concern for engineering across the entire stack from requirements management to monitoring and supporting production code.
Aligning all those processes remains unsolved.
Compound Engineering is what happens when agents write 100% of the code.
At @every, engineers don’t type code anymore. They orchestrate agents.
The shift:
- Coding is no longer the bottleneck
- Planning, review, and learning loops matter more than syntax
- Each feature makes the next one easier to build
The 4-step Compound Engineering loop:
1.Plan – Agents research the codebase + best practices and produce detailed plans
2.Work – Agents write code, tests, and iterate using real app simulations
3.Assess – Humans + AI review from multiple angles (security, performance, overbuild)
4.Compound – Lessons learned are stored so future agents never repeat mistakes
Complexity still grows, but so does the AI’s understanding of the system.
Result:
- One developer can now do the work of ~5
- Products run by single engineers serve thousands of users
- New hires instantly inherit years of institutional knowledge
Engineering is no longer about writing code.
It’s about designing learning systems that compound.
— Thanks @danshipper and @kieranklaassen for sharing your approach. So much to learn and takeaway from this compound engineering approach.

That save changed the history of soccer.
If that ball went in, Mbappe would have added his 2nd WC on top of winning the golden boot and having a hat-trick in a WC final, at 23.
Pele's + GOAT territory.
Messi would have been remembered as the greatest club player of all time.
