I hope not, my LLM detector is off if that's the case. But looking at how they've responded elsewhere it may be the case that they are pulling from LLMs to try and win arguments.

It definitely seems like they have a bunch of unconnected ways of arguing in this comment section. Like here they are arguing that the PCB design is the hardest act of engineering ever done. Elsewhere they are arguing that just seeing the schematics is all someone needs to build an iPhone.

Looking at their comment history outside this thread, I think they aren't always using LLMs. Perhaps just when something gets more technical than they have the experience for.
