It is still a bold claim and it still needs evidence.
We would obviously get a bit more of the evidence if it were to be more useful for the upcoming IPO than this rather open-ended, reinterpretable phrasing.
No, obviously. They'd be expected to do a substantially worse job and yet still drastically accelerate the design process.
LLMs make all sorts of dumb mistakes when writing c++ or python yet are nonetheless massively beneficial.
I've used GPT-5.5 and Opus both for FPGA design with good results. We built a lot of tooling around it to help the models, but even without that they're definitely capable of designing digital logic.
This actually plays out across every field and is well documented. An expert can recognize the hallucinations and bullshit coming out of LLMs, while non-experts see plausible output and do not know enough to know it is BS.
