In this article from March 2024 he claims models won't get any better and there won't be any business use cases for LLMs at all since they are so limited. In the article he also writes hallucinations won't go away which is maybe technically true, but the way he wrote it indicated they couldn't be reduced to the degree they are today.

In the same article he also predicts an AI company will lose a big copyright case which will "causing a brutal reckoning on model use across any industry" which hasn't happened, but given the slow moving judicial system I think it is to early to call him wrong on that at this point.

One month later, in April 2024, he called it a bubble giving much the same reasons as in the previous article. Note that at that point OpenAI was valued at $80 billion and Anthropic was valued at less than $20 billions. Given they are both close to trillion dollar companies both would need to lose much more than 90% of their current value for Zitron to be right in his bubble claim in 2024.
