Earlier quoted context omitted.
I don't think that's a very fair reason to disregard what a person is saying.
I have other reasons for ignoring Musk, such as his history of lying, exaggeration, personal attacks on people, provoking people. If he wants to talk about work from home in moral terms I can consider his own moral shortcomings and how he has no moral authority. But someone how says "like" repeatedly telegraphs confused thinking. Normally I hear that from teenagers, who have the excuse of youth.
Or it telegraphs that they're constantly reevaluating the assumptions behind what they're saying in real-time, unlike charismatic salespeople or politicians who will never use the word "like" because they are spewing unthinking bullshit.
I have the same evaluation of Musk as you do but don't agree with the comment about "like" usage.
