It's a good article. It seems like the author hedges his bets a little bit on the title question. At the end he allows that someday there could be a combination of LLMs, support scaffolding, and prompt engineering that will be able to tackle even the problems it has difficulty with now. But it was interesting as a tour through some seemingly straightforward problems that even the most advanced current LLMs are bad at, as well as containing interesting speculation on the root cause.
