Yes, they are about very different topics but in both fields having a lot of knowledge and experience is very valuable. That is how it is in all sciences and professions. Professionals with years of experience who do strong, well-reviewed and thoroughly tested work have a lot of trust. That is what I aim for as a programmer and what most scientists strive for. I know several scientists personally and all of them are smart people and excellent at what they do.
If you think their methods are flawed then please tell me what your evidence is that they made some horrible mistakes.
We know, because the media has fried a lot of doctors and drug companies.
