Brief

Emm0sh contends that AI progress in coding has outpaced understanding of how little current tools can change real-world engineering and manufacturing. The post says proprietary CAD and manufacturing platforms block interoperability, starving AI efforts of usable data, and argues that even AGI would not automatically accelerate physical production. It frames the challenge as organizational and data-structural, not purely technical, while predicting disruption across industrial software.

Why it matters

In a 397-word post published on 2026-02-21, emm0sh argues frontier AI has rapidly improved software engineering tools over the last six months, but that those gains will not translate directly to manufacturing or physical engineering work.

Key details

  • The post claims the main barrier in engineering and manufacturing is business structure rather than model capability: CAD and manufacturing incumbents restrict interoperability and keep data locked in proprietary systems, limiting the training data needed for AI systems.
  • Emm0sh argues LLMs alone are insufficient for non-software work because much of engineering is not text-based, citing Yann LeCun’s view, and says real corporate bottlenecks include software, hierarchy, and horizontal integration—not just human labor.

TLDR: Frontier AI companies can't solve engineering outside of software. It's not a technical problem, it's a business problem.

Warning: I'm writing this for my Series A raise, so if you hate founder-slop, you should stop reading now.

I don't think the non-software folks understand what has happened in the last six months to software engineering tools. It will be another six before they hear about it.

With that said, I don't think the frontier AI companies understand how little impact their tools will have on the real world. If we get AGI tomorrow, do your bolts get made faster? No.

Most of these companies do not understand how painful the real world is. There is no GitHub or Stack Overflow for Engineering and Manufacturing. This is by design. The incumbent software platforms do not want interoperability. It is how they make money -- through locking users and their data behind moats. Systems of Record? It's the Inglourious Basterds meme when I hear you say this -- you just told me you haven't had a job outside of B2B SaaS.

Not only do the incumbents not want you to have it, they will actively fight against you trying to get it. Ask any CEO in the CAD or manufacturing software space.

The problem for the people pursuing the future is that you need this data to train models. Even worse, LLMs will not be enough. I'm not an LLM doomer, but I do subscribe to the Yann LeCun school of thought. You can throw around infinite text data and giga-scale compute and get most of a SWE out of the other side, but most of other jobs is not text.

The theory Marcohard is betting on is that removing people is the only problem to be solved here. This is incorrect. People were never the only bottleneck in real corporations -- software, hierarchy and horizontal integration were. They're only getting rid of two of the four.

I do think that xAI actually knows this, but they are being quiet about their real plan to not give away the secret sauce.

So anyways, the tsunami is coming. It will destroy most of the engineering and manufacturing software ecosystem. The good news is that it will leave open beachheads. WORC is betting on this. If you want to be a part of it, let's chat about our Series A.
