It's nice to see someone in his position not trying to use it to bring about changes outside his area of expertise.
Political is a transversal subject and everybody should study and speak about it.
I was wondering why we must celebrate those who only speak within their domain of expertise -- which is why so few scientists/engineers make their voices heard even when the science they create is being trampled on.
This is the focus of the excellent "Manufacturing Ignorance" documentary: https://www.zed.fr/en/tv/distribution/catalogue/programme/ma...
"Must celebrate" is too strong. But a good reason to recommend such people is that such people are easier for most listeners to recognize as reliable source of information in the domain. People who are vocal of their unrelated political opinions can be experts on the domain, but they are more polarizing and make people watch out or reject them.
