That's cult-of-personality thinking. It invovles the fallacious argument "appeal to authority".

If I told you I was Tony Robbins and I was a multi-millionaire., would that sway you? I doubt it because, despite being someone who has been successful at business, he's likely not going to garner respect.

You should evaluated arguments-- technological or not-- on their logic, reason and scientific basis. And this is why those are the only kind of arguments I will make.

The counter arguments, however, tend to be naming "Authorities"... rathre than making logical or reasoned arguments.
