This is deeply untrue, and is highly likely to lead them to bad conclusions about what we can and should do with LLMs.
Claiming that LLMs are conscious or human-like because humans can't do X seems a very strange way to argue for LLM intelligence.
Usually, it goes the other way around: an LLM sceptic says "LLMs are dumb because they can't do X" and soon someone has to remind them that also most of the population can't, in fact, do X.
