Is the implication that those who aren't talking about it are a set of people for whom experiencing jhana was net neutral/negative for the people around them?
The implication is that people just don't spend much time talking about jhanas at all.
There are ~3,000 living billionaires. People talk about them continuously. Their actions are studied, their motives are studied, their contribution to society continuously assessed. The top few are household names.
There are countless living people who achieve jhanas. The topic comes up in conversation basically never. I know someone who I'd confidently say has gotten there. It hasn't yet inspired them to do anything new and they generally don't bring it up in conversation with people since it leads to a lot of woo and disagreement.
