I don't find that frustrating about his writing-- on the contrary, his colorful (tinted with derision) use of language is very soothing to me, especially after encountering relentless LLM optimists like yourself on here every day, and dealing with people who have AI psychosis and are in positions of power over me, every week.
Even if Zitron is hopelessly wrong and a complete fool, he's an engaging writer. Like the original article itself states, it's not about the numbers, it's about catharsis. The transparent absence of AI tells in his articles is refreshing, and just rampaging against the AI boosters who lack empathy and self-awareness (which so many of them absolutely do) is cathartic. Even if it's all bunk, fake, and stupid, it's nice to have a way to self-soothe and manifest how much some of us want AI to have a reckoning.
Does that make his readers suckers? Possibly. But personally I also think it's a very human trait to seek comfort.
If you find derision and extreme cynicism "soothing", the problem may be with you, rather than those who are optimistic about AI.
One of the best heuristics I've seen on whether there will be a fruitful outcome in taking someone seriously is how often they invoke labels (name calling, etc).
Hasn't failed - both in real life and online.
