[Davide Faconti @facontidavide]

I completely agree with @dhh.

Funny enough, I also wrote code (c++) for 25 years.
I also enjoyed it tremendously, but I stopped in January 2026. I have no regrets.

Face reality people, and embrace the future.

[Mehdi (e/λ) @BetterCallMedhi]

I spent time in Shenzhen last year and when I saw Merz come back from China saying Germans need to work more I immediately knew what broke his brain because I lived the exact same cognitive shock

my first week in Huaqiangbei I burned through 4 prototype iterations of a motor controller board for less than a thousand bucks total, back home a friend was working on something similar and spent over 12 thousand for a single revision that took almost two months to arrive

when you live that contrast in your own hands with your own project something permanently shifts in how you see the world and it goes way deeper than speed & cost

what Shenzhen actually built is a collective learning organism, imagine 20 PCB fabs 15 injection mold shops 30 component distributors and a hundred firmware freelancers all within a 2km radius, looks insanely redundant from the outside until you realize redundancy is actually information density in disguise

I watched this firsthand with an injection mold supplier I was working with, this guy had seen a hundred founders iterate similar thermal designs over 6 months so he proactively modified his tooling before I even opened my mouth, he knew what I needed before I knew what I needed, the intelligence lives in the relationships between the nodes and it compounds daily

the west thinks about manufacturing as a cost center you optimize by centralizing…

China accidentally built a distributed neural network of manufacturing intelligence where knowledge diffuses horizontally across thousands of agents faster than any single western company can process internally

so when Merz comes back and says we need to work a bit more I think he saw the problem but COMPLETELY misdiagnosed the solution, telling Germans to work harder is like telling a horse to gallop faster when the other side built a combustion engine

the gap is ARCHITECTURAL

it’s ecosystem density, you need a custom connector in Shenzhen you walk 200 meters, in Munich you send an email and wait 3 weeks

it’s iteration speed, parallel search vs sequential optimization at the system level, it’s risk tolerance, Chinese founders ship something broken on Monday fix it Tuesday ship again Wednesday while European companies are still in the approval phase for the pilot program of the feasibility study…

and Merz only saw the surface, what he missed is the tier 2 cities like Hefei Chengdu Wuhan replicating the Shenzhen model at scale right now

BYD going from irrelevant to outselling every european automaker combined in roughly 5 years, Huawei building its own 7nm chip under maximum sanctions when every analyst said it was physically impossible & behind all of that a government that treats advanced manufacturing as an existential national priority while europe debates whether AI needs another ethics committee

I think what we’re watching is the most asymmetric economic competition in modern history and most western leaders are still framing it as a productivity problem when it’s actually an ontological one

Europe & America are optimizing variables that China stopped tracking years ago meanwhile China is compounding on dimensions the west has no framework to even measure
Merz at least had the courage to name

it out loud and I respect that genuinely but working a bit more inside a broken architecture just means you arrive at the wrong destination slightly faster

Robots don’t fail at the task.
They fail at recovery.

Cortex 1.5 introduces interactive policy patching:
short human corrections + online RL
→ robots improve after deployment.

No retraining. No rules.
Just better behavior in production.

-the @SereactAI way-

The robotics world is slowly diverging from the previous consensus view that a research-only approach would lead to a ChatGPT-like breakthrough in the field.

Both recent pieces from @packyM and @oyhsu allude to a more step-by-step approach towards general robotic intelligence.

The reality is that real-world data is the only source where modalities, scale, and deployment distributions converge.

As such, exposing frontier robotics models directly to real production environments allows them to learn from live operations and align training and deployment distributions.

That's what then unlocks new use-cases (at the accuracy level customers demand), new embodiments, and the path to generalization.

Our portfolio company @SereactAI has been quietly building in this direction over the past couple of years, site by site deployment, scaling their real-world data loop while delivering outstanding customer value and unlocking new use cases and markets.

Not just demos. Real-world systems in production. All running on the same model, regardless of the use-case or robotic platform.

This is the way 🦾

[Mathias Mantelli @MathiasMantelli]

@audrow Totally understandable, even though it will be missed. Take care of yourself and your family.

@chris_j_paxton It's a cool video indeed :)
But am I the only one who noticed the double-sided tape around the Thor (to maybe help the robot pick it) and potentially on top of the dog as well? 🤔
