It matters the same way saying “solar panels are super expensive” has been historically true not too long ago, but prices have fallen so rapidly it’s simply no longer a correct statement - even if you will occasionally come across an overpriced offer here and there.
I feel like we're arguing over semantics. What op quoted, referring to what I imagine were things like: confidently running wrong commands, answering something without looking it up, getting stuck on long scripts and not self-correcting all absolutely still happen, so the statement isn't incorrect.
I would also wager that OOP knows LLM limits quite well, and a more interesting discussion would be for why someone perceives LLMs as dumb as opposed to speculating whether they're aware of the frontier or not.
