I think the points you raise are reasonable signals to consider, but I don't think they show the author being "consistently wrong". The overall thesis still remains plausible even though we have seen LLMs continue to improve.

> - hallucinations are dramatically less of a problem

Sure, but it remains a big enough problem that human intervention and review is still necessary for any serious work across all use cases and industries.

> - several mass market use cases have emerged, most notably coding

Coding seems to be the only one, but there are still a lot of open questions about how the market can sustain the costs, and that's without considering the market dynamics that could emerge once costs are lowered enough that open source models start to become an attractive option.

> - rate of progress has increased

Debatable.
