I have followed Clif's work a very long time. I don't always agree with everything he says but I love where he is lately. He's awakening so fast now its wonderful to watch.
Clif is a logician (programmer) and linguist by training. I come from a similar logic background and I have worked with natural language systems in the early 1990s. A system I and a young man from MIT reverse engineered, became the software which was Google Translate until 2009, which they the switched into using neural networks (a better tech honestly).
Clif's software that analyzes the words from social media tends to skew to the negative and scary side of things about 100 to 1, over positive outcomes (from my observation) so I always keep that in mind. It has to do with the fact that humans are more expressive when things are bad. Still he often has some really interesting insights.
I really think the human body is much more resilient to the mRNA vaccines than people think, but it could weaken people for a bit. I have a loved one who took the Pfizer vaccine, despite my encouraging them not to. So I am hoping for the best on that.
